Display Name: EditVehicleRoutingProblem

Description: EditVehicleRoutingProblem tool solves a vehicle routing problem (VRP) to find the best routes for a fleet of vehicles. It is similar to SolveVehicleRoutingProblem, but EditVehicleRoutingProblem is designed to make a few, small edits to the results of a vehicle routing problem and re-solve or solve a small VRP analysis of only two routes. A dispatcher managing a fleet of vehicles is often required to make decisions about vehicle routing. One such decision involves how to best assign a group of customers to a fleet of vehicles and to sequence and schedule their visits. The objectives in solving such vehicle routing problems (VRP) are to provide a high level of customer service by honoring any time windows while keeping the overall operating and investment costs for each route as low as possible. The constraints are to complete the routes with available resources and within the time limits imposed by driver work shifts, driving speeds, and customer commitments., This service can be used to determine solutions for such complex fleet management tasks. Consider an example of delivering goods to grocery stores from a central warehouse location. A fleet of three trucks is available at the warehouse. The warehouse operates only within a certain time window—from 8:00 a.m. to 5:00 p.m.—during which all trucks must return back to the warehouse. Each truck has a capacity of 15,000 pounds, which limits the amount of goods it can carry. Each store has a demand for a specific amount of goods (in pounds) that needs to be delivered, and each store has time windows that confine when deliveries should be made. Furthermore, the driver can work only eight hours per day, requires a break for lunch, and is paid for the time spent on driving and servicing the stores. The goal is to come up with an itinerary for each driver (or route) such that the deliveries can be made while honoring all the service requirements and minimizing the total time spent on a particular route by the driver.

Execution Type: esriExecutionTypeSynchronous

Parameters:

Parameter: orders

Data Type: GPFeatureRecordSetLayer
Display Name Orders
Description: Specify one or more orders (up to 100). These are the locations that the routes of the vehicle routing problem (VRP) analysis should visit. An order can represent a delivery (for example, furniture delivery), a pickup (such as an airport shuttle bus picking up a passenger), or some type of service or inspection (a tree trimming job or building inspection, for instance). When specifying the orders, you can set properties for each one, such as its name or service time, by using attributes. The orders can be specified with the following attributes: ObjectID: The system-managed ID field. Name: The name of the order. The name must be unique. If the name is left null, a name is automatically generated at solve time. ServiceTime: This property specifies how much time will be spent at the network location when the route visits it; that is, it stores the impedance value for the network location. A zero or null value indicates the network location requires no service time. The unit for this field value is specified by the time_units parameter. TimeWindowStart1: The beginning time of the first time window for the network location. This field can contain a null value; a null value indicates no beginning time. A time window only states when a vehicle can arrive at an order; it doesn't state when the service time must be completed. To account for service time and leave before the time window is over, subtract ServiceTime from the TimeWindowEnd1 field. The time window fields can contain a time-only value or a date and time value. If a time field such as TimeWindowStart1 has a time-only value (for example, 8:00 AM), the date is assumed to be the date specified by the Default Date parameter. Using date and time values (for example, 7/11/2010 8:00 AM) allows you to set time windows that span multiple days. When solving a problem that spans multiple time zones, each order's time-window values refer to the time zone in which the order is located. TimeWindowEnd1: The ending time of the first window for the network location. This field can contain a null value; a null value indicates no ending time. TimeWindowStart2: The beginning time of the second time window for the network location. This field can contain a null value; a null value indicates that there is no second time window. If the first time window is null, as specified by the TimeWindowStart1 and TimeWindowEnd1 fields, the second time window must also be null. If both time windows are nonnull, they can't overlap. Also, the second time window must occur after the first. TimeWindowEnd2: The ending time of the second time window for the network location. This field can contain a null value. When TimeWindowStart2 and TimeWindowEnd2 are both null, there is no second time window. When TimeWindowStart2 is not null but TimeWindowEnd2 is null, there is a second time window that has a starting time but no ending time. This is valid. MaxViolationTime1: A time window is considered violated if the arrival time occurs after the time window has ended. This field specifies the maximum allowable violation time for the first time window of the order. It can contain a zero value but can't contain negative values. A zero value indicates that a time window violation at the first time window of the order is unacceptable; that is, the first time window is hard. On the other hand, a null value indicates that there is no limit on the allowable violation time. A nonzero value specifies the maximum amount of lateness; for example, a route can arrive at an order up to 30 minutes beyond the end of its first time window. The unit for this field value is specified by the Time Field Units parameter Time window violations can be tracked and weighted by the solver. Because of this, you can direct the VRP solver to take one of three approaches: Minimize the overall violation time, regardless of the increase in travel cost for the fleet. Find a solution that balances overall violation time and travel cost. Ignore the overall violation time; instead, minimize the travel cost for the fleet. By assigning an importance level for the Time Window Violation Importance parameter, you are essentially choosing one of these three approaches. In any case, however, the solver will return an error if the value set for MaxViolationTime1 is surpassed. MaxViolationTime2: The maximum allowable violation time for the second time window of the order. This field is analogous to the MaxViolationTime1 field. InboundArriveTime: Defines when the item to be delivered to the order will be ready at the starting depot. The order can be assigned to a route only if the inbound arrive time precedes the route's latest start time value; this way, the route cannot leave the depot before the item is ready to be loaded onto it. This field can help model scenarios involving inbound-wave transshipments. For example, a job at an order requires special materials that are not currently available at the depot. The materials are being shipped from another location and will arrive at the depot at 11:00 a.m. To ensure a route that leaves before the shipment arrives isn't assigned to the order, the order's inbound arrive time is set to 11:00 a.m. The special materials arrive at 11:00 a.m., they are loaded onto the vehicle, and the vehicle departs from the depot to visit its assigned orders. Notes:The route's start time, which includes service times, must occur after the inbound arrive time. If a route begins before an order's inbound arrive time, the order cannot be assigned to the route. The assignment is invalid even if the route has a start-depot service time that lasts until after the inbound arrive time.This time field can contain a time-only value or a date and time value. If a time-only value is set (for example, 11:00 AM), the date is assumed to be the date specified by the Default Date parameter. The default date is ignored, however, when any time field in the Depots, Routes, Orders, or Breaks includes a date with the time. In that case, specify all such fields with a date and time (for example, 7/11/2015 11:00 AM).The VRP solver honors InboundArriveTime regardless of the DeliveryQuantities value.If an outbound depart time is also specified, its time value must occur after the inbound arrive time. OutboundDepartTime: Defines when the item to be picked up at the order must arrive at the ending depot. The order can be assigned to a route only if the route can visit the order and reach its end depot before the specified outbound depart time. This field can help model scenarios involving outbound-wave transshipments. For instance, a shipping company sends out delivery trucks to pick up packages from orders and bring them into a depot where they are forwarded on to other facilities, en route to their final destination. At 3:00 p.m. every day, a semitrailer stops at the depot to pick up the high-priority packages and take them directly to a central processing station. To avoid delaying the high-priority packages until the next day's 3:00 p.m. trip, the shipping company tries to have delivery trucks pick up the high-priority packages from orders and bring them to the depot before the 3:00 p.m. deadline. This is done by setting the outbound depart time to 3:00 p.m. Notes:The route's end time, including service times, must occur before the outbound depart time. If a route reaches a depot but doesn't complete its end-depot service time prior to the order's outbound depart time, the order cannot be assigned to the route. This time field can contain a time-only value or a date and time value. If a time-only value is set (for example, 11:00 AM), the date is assumed to be the date specified by the Default Date parameter. The default date is ignored, however, when any time field in Depots, Routes, Orders, or Breaks includes a date with the time. In that case, specify all such fields with a date and time (for example, 7/11/2015 11:00 AM).The VRP solver honors OutboundDepartTime regardless of the PickupQuantities value.If an inbound arrive time is also specified, its time value must occur before the outbound depart time. DeliveryQuantities: The size of the delivery. You can specify size in any dimension you want, such as weight, volume, or quantity. You can even specify multiple dimensions, for example, weight and volume. Enter delivery quantities without indicating units. For example, if a 300-pound object needs to be delivered to an order, enter 300. You will need to remember that the value is in pounds. If you are tracking multiple dimensions, separate the numeric values with a space. For instance, if you are recording the weight and volume of a delivery that weighs 2,000 pounds and has a volume of 100 cubic feet, enter 2000 100. Again, you need to remember the units—in this case, pounds and cubic feet. You also need to remember the sequence in which the values and their corresponding units are entered. Make sure that Capacities for Routes and DeliveryQuantities and PickupQuantities for Orders are specified in the same manner; that is, the values need to be in the same units, and if you are using multiple dimensions, the dimensions need to be listed in the same sequence for all parameters. So if you specify weight in pounds, followed by volume in cubic feet for DeliveryQuantities, the capacity of your routes and the pickup quantities of your orders need to be specified the same way: weight in pounds, then volume in cubic feet. If you mix units or change the sequence, you will get unwanted results without receiving any warning messages. An empty string or null value is equivalent to all dimensions being zero. If the string has an insufficient number of values in relation to the capacity count, or dimensions being tracked, the remaining values are treated as zeros. Delivery quantities can't be negative. PickupQuantities: The size of the pickup. You can specify size in any dimension you want, such as weight, volume, or quantity. You can even specify multiple dimensions, for example, weight and volume. You cannot, however, use negative values. This field is analogous to the DeliveryQuantities field of Orders. In the case of an exchange visit, an order can have both delivery and pickup quantities. Revenue: The income generated if the order is included in a solution. This field can contain a null value—a null value indicates zero revenue—but it can't have a negative value. Revenue is included in optimizing the objective function value but is not part of the solution's operating cost; that is, the TotalCost field in the route class never includes revenue in its output. However, revenue weights the relative importance of servicing orders. SpecialtyNames: A space-separated string containing the names of the specialties required by the order. A null value indicates that the order doesn't require specialties. The spelling of any specialties listed in the Orders and Routes classes must match exactly so that the VRP solver can link them together. To illustrate what specialties are and how they work, assume a lawn care and tree trimming company has a portion of its orders that requires a bucket truck to trim tall trees. The company would enter BucketTruck in the SpecialtyNames field for these orders to indicate their special need. SpecialtyNames would be left as null for the other orders. Similarly, the company would also enter BucketTruck in the SpecialtyNames field of routes that are driven by trucks with hydraulic booms. It would leave the field null for the other routes. At solve time, the VRP solver assigns orders without special needs to any route, but it only assigns orders that need bucket trucks to routes that have them. AssignmentRule: This field specifies the rule for assigning the order to a route. It is constrained by a domain of values, which are listed below (use the numeric code, not the name in parentheses). 0 (Exclude)—The order is to be excluded from the subsequent solve operation.1 (Preserve route and relative sequence)—The solver must always assign the order to the preassigned route and at the preassigned relative sequence during the solve operation. If this assignment rule can't be followed, it results in an order violation. With this setting, only the relative sequence is maintained, not the absolute sequence. To illustrate what this means, imagine there are two orders: A and B. They have sequence values of 2 and 3, respectively. If you set their AssignmentRule field values to Preserve route and relative sequence, A and B's actual sequence values may change after solving because other orders, breaks, and depot visits could still be sequenced before, between, or after A and B. However, B cannot be sequenced before A. 2 (Preserve route)—The solver must always assign the order to the preassigned route during the solve operation. A valid sequence must also be set even though the sequence may or may not be preserved. If the order can't be assigned to the specified route, it results in an order violation.3 (Override)—The solver tries to preserve the route and sequence preassignment for the order during the solve operation. However, a new route or sequence for the order may be assigned if it helps minimize the overall value of the objective function. This is the default value.4 (Anchor first)—The solver ignores the route and sequence preassignment (if any) for the order during the solve operation. It assigns a route to the order, and makes it the first order on that route, so as to minimize the overall value of the objective function.5 (Anchor last)—The solver ignores the route and sequence preassignment (if any) for the order during the solve operation. It assigns a route to the order, and makes it the last order on that route, so as to minimize the overall value of the objective function. This field can't contain a null value. CurbApproach: Specifies the direction a vehicle may arrive at and depart from the order. The field value is specified as one of the following integers shown in the parentheses (use the numeric code, not the name in parentheses): 0 (Either side of vehicle)—The vehicle can approach and depart the order in either direction, so a U-turn is allowed at the incident. This setting can be chosen if it is possible and desirable for your vehicle to turn around at the order. This decision may depend on the width of the road and the amount of traffic or whether the order has a parking lot where vehicles can pull in and turn around. 1 (Right side of vehicle)—When the vehicle approaches and departs the order, the order must be on the right side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the right-hand side. 2 (Left side of vehicle)—When the vehicle approaches and departs the order, the curb must be on the left side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the left-hand side. 3 (No U-Turn)—When the vehicle approaches the order, the curb can be on either side of the vehicle; however, the vehicle must depart without turning around. The CurbApproach property is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an order on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach an order from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to arrive at an order and not have a lane of traffic between the vehicle and the order, you would choose 1 (Right side of vehicle) in the United States but 2 (Left side of vehicle) in the United Kingdom. RouteName: The name of the route to which the order is assigned. As an input field, this field is used to preassign an order to a specific route. It can contain a null value, indicating that the order is not preassigned to any route, and the solver determines the best possible route assignment for the order. If this is set to null, the sequence field must also be set to null. After a solve operation, if the order is routed, the RouteName field contains the name of the route that the order is assigned to. Sequence: This indicates the sequence of the order on its assigned route. As an input field, this field is used to specify the relative sequence for an order on the route. This field can contain a null value specifying that the order can be placed anywhere along the route. A null value can only occur together with a null RouteName value. The input sequence values are positive and unique for each route (shared across renewal depot visits, orders, and breaks), but do not need to start from 1 or be contiguous. After a solve operation, the Sequence field contains the sequence value of the order on its assigned route. Output sequence values for a route are shared across depot visits, orders, and breaks; start from 1 (at the starting depot); and are consecutive. So the smallest possible output sequence value for a routed order is 2, since a route always begins at a depot.

Parameter: depots

Data Type: GPFeatureRecordSetLayer
Display Name Depots
Description: Specify one or more depots for the given VRP. A depot is a location that a vehicle departs from at the beginning of its workday and returns to at the end of the workday. Vehicles are loaded (for deliveries) or unloaded (for pickups) at depots at the start of the route. In some cases, a depot can also act as a renewal location whereby the vehicle can unload or reload and continue performing deliveries and pickups. A depot has open and close times, as specified by a hard time window. Vehicles can't arrive at a depot outside of this time window. When specifying the orders, you can set properties for each one, such as its name or service time, using attributes. The orders can be specified with the following attributes: ObjectID: The system-managed ID field. Name: The name of the depot. The StartDepotName and EndDepotName fields of the Routes record set reference the names you specify here. It is also referenced by the Route Renewals record set, when used. Depot names are case insensitive and have to be nonempty and unique. TimeWindowStart1: The beginning time of the first time window for the network location. This field can contain a null value; a null value indicates no beginning time. Time window fields can contain a time-only value or a date and time value. If a time field has a time-only value (for example, 8:00 AM), the date is assumed to be the date specified by the Default Date parameter of the analysis layer. Using date and time values (for example, 7/11/2010 8:00 AM) allows you to set time windows that span multiple days. When solving a problem that spans multiple time zones, each depot's time-window values refer to the time zone in which the depot is located. TimeWindowEnd1: The ending time of the first window for the network location. This field can contain a null value; a null value indicates no ending time. TimeWindowStart2: The beginning time of the second time window for the network location. This field can contain a null value; a null value indicates that there is no second time window. If the first time window is null, as specified by the TimeWindowStart1 and TimeWindowEnd1 fields, the second time window must also be null. If both time windows are nonnull, they can't overlap. Also, the second time window must occur after the first. TimeWindowEnd2: The ending time of the second time window for the network location. This field can contain a null value. When TimeWindowStart2 and TimeWindowEnd2 are both null, there is no second time window. When TimeWindowStart2 is not null but TimeWindowEnd2 is null, there is a second time window that has a starting time but no ending time. This is valid. CurbApproach: Specifies the direction a vehicle may arrive at and depart from the depot. The field value is specified as one of the following integers shown in the parentheses (use the numeric code, not the name in parentheses): 0 (Either side of vehicle)—The vehicle can approach and depart the depot in either direction, so a U-turn is allowed at the incident. This setting can be chosen if it is possible and desirable for your vehicle to turn around at the depot. This decision may depend on the width of the road and the amount of traffic or whether the depot has a parking lot where vehicles can pull in and turn around. 1 (Right side of vehicle)—When the vehicle approaches and departs the depot, the depot must be on the right side of the vehicle. A U-turn is prohibited. This is typically used for vehicles like buses that must arrive with the bus stop on the right-hand side. 2 (Left side of vehicle)—When the vehicle approaches and departs the depot, the curb must be on the left side of the vehicle. A U-turn is prohibited. This is typically used for vehicles like buses that must arrive with the bus stop on the left-hand side. 3 (No U-Turn)—When the vehicle approaches the depot, the curb can be on either side of the vehicle; however, the vehicle must depart without turning around. The CurbApproach property is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider a depot on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach a depot from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to arrive at a depot and not have a lane of traffic between the vehicle and the depot, you would choose 1 (Right side of vehicle) in the United States but 2 (Left side of vehicle) in the United Kingdom. Bearing: The direction in which a point is moving. The units are degrees and are measured in a clockwise fashion from true north. This field is used in conjunction with the BearingTol field. Bearing data is usually sent automatically from a mobile device that is equipped with a GPS receiver. Try to include bearing data if you are loading an order that is moving, such as a pedestrian or a vehicle. Using this field tends to prevent adding locations to the wrong edges, which can occur when a vehicle is near an intersection or an overpass, for example. Bearing also helps the tool determine which side of the street the point is on. For more information, see the Bearing and Bearing Tolerance Help topic (http://links.esri.com/bearing-and-bearing-tolerance). BearingTol: The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing field. If the value from the Bearing field is within the range of acceptable values that are generated from the bearing tolerance on an edge, the point can be added as a network location there; otherwise, the closest point on the next-nearest edge is evaluated. The units are in degrees, and the default value is 30. Values must be greater than zero and less than 180. A value of 30 means that when Network Analyst attempts to add a network location on an edge, a range of acceptable bearing values is generated 15 degrees to either side of the edge (left and right) and in both digitized directions of the edge. For more information, see the Bearing and Bearing Tolerance topic in the ArcGIS help system (http://links.esri.com/bearing-and-bearing-tolerance). NavLatency: This field is only used in the solve process if Bearing and BearingTol also have values; however, entering a NavLatency value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much time is expected to elapse from the moment GPS information is sent from a moving vehicle to a server and the moment the processed route is received by the vehicle's navigation device. The time units of NavLatency are the same as the units of the cost attribute specified by the parameter Time Attribute.

Parameter: routes

Data Type: GPRecordSet
Display Name Routes
Description: Specify one or more routes (up to 2). A route specifies vehicle and driver characteristics; after solving, it also represents the path between depots and orders. A route can have start and end depot service times, a fixed or flexible starting time, time-based operating costs, distance-based operating costs, multiple capacities, various constraints on a driver's workday, and so on. When specifying the routes, you can set properties for each one by using attributes. The routes can be specified with the following attributes: Name: The name of the route. The name must be unique. The tool generates a unique name at solve time if the field value is null; therefore, entering a value is optional in most cases. However, you must enter a name if your analysis includes breaks, route renewals, route zones, or orders that are preassigned to a route because the route name is used as a foreign key in these cases. Note that route names are case insensitive. StartDepotName: The name of the starting depot for the route. This field is a foreign key to the Name field in Depots. If the StartDepotName value is null, the route will begin from the first order assigned. Omitting the start depot is useful when the vehicle's starting location is unknown or irrelevant to your problem. However, when StartDepotName is null, EndDepotName cannot also be null. Virtual start depots are not allowed if orders or depots are in multiple time zones If the route is making deliveries and StartDepotName is null, it is assumed the cargo is loaded on the vehicle at a virtual depot before the route begins. For a route that has no renewal visits, its delivery orders (those with nonzero DeliveryQuantities values in the Orders class) are loaded at the start depot or virtual depot. For a route that has renewal visits, only the delivery orders before the first renewal visit are loaded at the start depot or virtual depot. EndDepotName: The name of the ending depot for the route. This field is a foreign key to the Name field in the Depots class. StartDepotServiceTime: The service time at the starting depot. This can be used to model the time spent loading the vehicle. This field can contain a null value; a null value indicates zero service time. The unit for this field value is specified by the Time Field Units parameter. The service times at the start and end depots are fixed values (given by the StartDepotServiceTime and EndDepotServiceTime field values) and do not take into account the actual load for a route. For example, the time taken to load a vehicle at the starting depot may depend on the size of the orders. As such, the depot service times could be given values corresponding to a full truckload or an average truckload, or you could make your own time estimate. EndDepotServiceTime: The service time at the ending depot. This can be used to model the time spent unloading the vehicle. This field can contain a null value; a null value indicates zero service time. The unit for this field value is specified by the Time Field Units parameter. The service times at the start and end depots are fixed values (given by the StartDepotServiceTime and EndDepotServiceTime field values) and do not take into account the actual load for a route. For example, the time taken to load a vehicle at the starting depot may depend on the size of the orders. As such, the depot service times could be given values corresponding to a full truckload or an average truckload, or you could make your own time estimate. EarliestStartTime: The earliest allowable starting time for the route. This is used by the solver in conjunction with the time window of the starting depot for determining feasible route start times. This field can't contain null values and has a default time-only value of 8:00 AM; the default value is interpreted as 8:00 a.m. on the date given by the Default Date parameter. When solving a problem that spans multiple time zones, the time zone for EarliestStartTime is the same as the time zone in which the starting depot is located. LatestStartTime: The latest allowable starting time for the route. This field can't contain null values and has a default time-only value of 10:00 AM; the default value is interpreted as 10:00 a.m. on the date given by the Default Date property of the analysis layer. When solving a problem that spans multiple time zones, the time zone for LatestStartTime is the same as the time zone in which the starting depot is located. ArriveDepartDelay: This field stores the amount of travel time needed to accelerate the vehicle to normal travel speeds, decelerate it to a stop, and move it off and on the network (for example, in and out of parking). By including an ArriveDepartDelay value, the VRP solver is deterred from sending many routes to service physically coincident orders. The cost for this property is incurred between visits to noncoincident orders, depots, and route renewals. For example, when a route starts from a depot and visits the first order, the total arrive/depart delay is added to the travel time. The same is true when traveling from the first order to the second order. If the second and third orders are coincident, the ArriveDepartDelay value is not added between them since the vehicle doesn't need to move. If the route travels to a route renewal, the value is added to the travel time again. Although a vehicle needs to slow down and stop for a break and accelerate afterwards, the VRP solver cannot add the ArriveDepartDelay value for breaks. This means that if a route leaves an order, stops for a break, and continues to the next order, the arrive/depart delay is added only once, not twice. To illustrate, assume there are five coincident orders in a high-rise building, and they are serviced by three different routes. This means three arrive/depart delays would be incurred; that is, three drivers would need to separately find parking places and enter the same building. However, if the orders could be serviced by just one route instead, only one driver would need to park and enter the building—only one arrive/depart delay would be incurred. Since the VRP solver tries to minimize cost, it will try to limit the arrive/depart delays and thus choose the single-route option. (Note that multiple routes may need to be sent when other constraints—such as specialties, time windows, or capacities—require it.) The unit for this field value is specified by the time_units parameter. Capacities: The maximum capacity of the vehicle. You can specify capacity in any dimension you want, such as weight, volume, or quantity. You can even specify multiple dimensions; for example, weight and volume. Enter capacities without indicating units. For example, assume your vehicle can carry a maximum of 40,000 pounds; you would enter 40000. You need to remember for future reference that the value is in pounds. If you are tracking multiple dimensions, separate the numeric values with a space. For instance, if you are recording both weight and volume and your vehicle can carry a maximum weight of 40,000 pounds and a maximum volume of 2,000 cubic feet, Capacities should be entered as 40000 2000. Again, you need to remember the units. You also need to remember the sequence in which the values and their corresponding units are entered (pounds followed by cubic feet in this case). Remembering the units and the unit sequence is important for a couple of reasons: one, so you can reinterpret the information later; and two, so you can properly enter values for the DeliveryQuantities and PickupQuantities fields for the orders. To elaborate on the second point, note that the VRP solver simultaneously refers to Capacities, DeliveryQuantities, and PickupQuantities to make sure that a route doesn't become overloaded. Since units can't be entered in the field, the VRP tool can't make unit conversions, so you need to enter the values for the three fields using the same units and the same unit sequence to ensure the values are correctly interpreted. If you combine units or change the sequence in any of the three fields, you will get unwanted results without receiving any warning messages. Thus, it is a good idea to set up a unit and unit-sequence standard beforehand and continually refer to it whenever entering values for these three fields. An empty string or null value is equivalent to all values being zero. Capacity values can't be negative. If the Capacities string has an insufficient number of values in relation to the DeliveryQuantities or PickupQuantities fields for orders, the remaining values are treated as zero. The VRP solver only performs a simple Boolean test to determine whether capacities are exceeded. If a route's capacity value is greater than or equal to the total quantity being carried, the VRP solver will assume the cargo fits in the vehicle. This could be incorrect, depending on the actual shape of the cargo and the vehicle. For example, the VRP solver allows you to fit a 1,000-cubic-foot sphere into a 1,000-cubic-foot truck that is 8 feet wide. In reality, however, since the sphere is 12.6 feet in diameter, it won't fit in the 8-foot wide truck. FixedCost: A fixed monetary cost that is incurred only if the route is used in a solution (that is, it has orders assigned to it). This field can contain null values; a null value indicates a zero-fixed cost. This cost is part of the total route operating cost. CostPerUnitTime: The monetary cost incurred—per unit of work time—for the total route duration, including travel times as well as service times and wait times at orders, depots, and breaks. This field can't contain a null value and has a default value of 1.0. The unit for this field value is specified by the time_units parameter. CostPerUnitDistance: The monetary cost incurred—per unit of distance traveled—for the route length (total travel distance). This field can contain null values; a null value indicates zero cost. The unit for this field value is specified by the distance_units parameter. OvertimeStartTime: The duration of regular work time before overtime computation begins. This field can contain null values; a null value indicates that overtime does not apply. The unit for this field value is specified by the time_units parameter. For example, if the driver is to be paid overtime pay when the total route duration extends beyond eight hours, OvertimeStartTime is specified as 480 (8 hours * 60 minutes/hour), given the time_units parameter is set to Minutes. CostPerUnitOvertime: The monetary cost incurred per time unit of overtime work. This field can contain null values; a null value indicates that the CostPerUnitOvertime value is the same as the CostPerUnitTime value. MaxOrderCount: The maximum allowable number of orders on the route. This field can't contain null values and has a default value of 30. MaxTotalTime: The maximum allowable route duration. The route duration includes travel times as well as service and wait times at orders, depots, and breaks. This field can contain null values; a null value indicates that there is no constraint on the route duration. The unit for this field value is specified by the time_units parameter. MaxTotalTravelTime: The maximum allowable travel time for the route. The travel time includes only the time spent driving on the network and does not include service or wait times. This field can contain null values; a null value indicates there is no constraint on the maximum allowable travel time. This field value can't be larger than the MaxTotalTime field value. The unit for this field value is specified by the time_units parameter. MaxTotalDistance: The maximum allowable travel distance for the route. The unit for this field value is specified by the distance_units parameter. This field can contain null values; a null value indicates that there is no constraint on the maximum allowable travel distance. SpecialtyNames: A space-separated string containing the names of the specialties supported by the route. A null value indicates that the route does not support any specialties. This field is a foreign key to the SpecialtyNames field in the Orders class. To illustrate what specialties are and how they work, assume a lawn care and tree trimming company has a portion of its orders that requires a bucket truck to trim tall trees. The company would enter BucketTruck in the SpecialtyNames field for these orders to indicate their special need. SpecialtyNames would be left as null for the other orders. Similarly, the company would also enter BucketTruck in the SpecialtyNames field of routes that are driven by trucks with hydraulic booms. It would leave the field null for the other routes. At solve time, the VRP solver assigns orders without special needs to any route, but it only assigns orders that need bucket trucks to routes that have them. AssignmentRule: This specifies whether or not the route can be used when solving the problem. This field is constrained by a domain of values, which are listed below (use the numeric code, not the name in parentheses). 1 (Include)—The route is included in the solve operation. This is the default value. 2 (Exclude)—The route is excluded from the solve operation.

Parameter: breaks

Data Type: GPRecordSet
Display Name Breaks
Description: These are the rest periods, or breaks, for the routes in a given VRP. A break is associated with exactly one route, and it can be taken after completing an order, while en route to an order, or prior to servicing an order. It has a start time and a duration, for which the driver may or may not be paid. There are three options for establishing when a break begins: using a time window, a maximum travel time, or a maximum work time. When specifying the breaks, you can set properties for each one, such as its name or service time, using attributes. The orders can be specified with the following attributes: ObjectID: The system-managed ID field. RouteName: The name of the route to which the break applies. Although a break is assigned to exactly one route, many breaks can be assigned to the same route. This field is a foreign key to the Name field in the routes parameter, so it can't have a null value. Precedence: Precedence values sequence the breaks of a given route. Breaks with a precedence value of 1 occur before those with a value of 2, and so on. All breaks must have a precedence value, regardless of whether they are time-window, maximum-travel-time, or maximum-work-time breaks. ServiceTime: The duration of the break. This field can contain null values; a null value indicates no service time. The unit for this field value is specified by the time_units parameter. TimeWindowStart: The starting time of the break's time window. If this field is null and TimeWindowEnd has a valid time-of-day value, the break is allowed to start any time before the TimeWindowEnd value. If this field has a value, the MaxTravelTimeBetweenBreaks and MaxCumulWorkTime field values must be null; moreover, all other breaks in the analysis layer must have null values for MaxTravelTimeBetweenBreaks and MaxCumulWorkTime. An error will occur at solve time if a route has multiple breaks with overlapping time windows. The time window fields in breaks can contain a time-only value or a date and time value. If a time field, such as TimeWindowStart, has a time-only value (for example, 12:00 PM), the date is assumed to be the date specified by the default_date parameter. Using date and time values (for example, 7/11/2012 12:00 PM) allows you to specify time windows that span two or more days. This is especially beneficial when a break should be taken sometime before and after midnight. When solving a problem that spans multiple time zones, each break's time-window values refer to the time zone in which the associated route, as specified by the RouteName field, is located. TimeWindowEnd: The ending time of the break's time window. If this field is null and TimeWindowStart has a valid time-of-day value, the break is allowed to start any time after the TimeWindowStart value. If this field has a value, MaxTravelTimeBetweenBreaks and MaxCumulWorkTime must be null; moreover, all other breaks in the analysis layer must have null values for MaxTravelTimeBetweenBreaks and MaxCumulWorkTime. MaxViolationTime: This field specifies the maximum allowable violation time for a time-window break. A time window is considered violated if the arrival time falls outside the time range. A zero value indicates the time window cannot be violated; that is, the time window is hard. A nonzero value specifies the maximum amount of lateness; for example, the break can begin up to 30 minutes beyond the end of its time window, but the lateness is penalized as per the Time Window Violation Importance parameter. This property can be null; a null value with TimeWindowStart and TimeWindowEnd values indicates that there is no limit on the allowable violation time. If MaxTravelTimeBetweenBreaks or MaxCumulWorkTime has a value, MaxViolationTime must be null. The unit for this field value is specified by the time_units parameter. MaxTravelTimeBetweenBreaks: The maximum amount of travel time that can be accumulated before the break is taken. The travel time is accumulated either from the end of the previous break or, if a break has not yet been taken, from the start of the route. If this is the route's final break, MaxTravelTimeBetweenBreaks also indicates the maximum travel time that can be accumulated from the final break to the end depot. This field is designed to limit how long a person can drive until a break is required. For instance, if the Time Field Units parameter (time_units for Python) of the analysis is set to Minutes, and MaxTravelTimeBetweenBreaks has a value of 120, the driver will get a break after two hours of driving. To assign a second break after two more hours of driving, the second break's MaxTravelTimeBetweenBreaks property should be 120. If this field has a value, TimeWindowStart, TimeWindowEnd, MaxViolationTime, and MaxCumulWorkTime must be null for an analysis to solve successfully. The unit for this field value is specified by the time_units parameter. MaxCumulWorkTime: The maximum amount of work time that can be accumulated before the break is taken. Work time is always accumulated from the beginning of the route. Work time is the sum of travel time and service times at orders, depots, and breaks. Note, however, that this excludes wait time, which is the time a route (or driver) spends waiting at an order or depot for a time window to begin. This field is designed to limit how long a person can work until a break is required. For instance, if the time_units parameter is set to Minutes, MaxCumulWorkTime has a value of 120, and ServiceTime has a value of 15, the driver will get a 15-minute break after two hours of work. Continuing with the last example, assume a second break is needed after three more hours of work. To specify this break, you would enter 315 (five hours and 15 minutes) as the second break's MaxCumulWorkTime value. This number includes the MaxCumulWorkTime and ServiceTime values of the preceding break, along with the three additional hours of work time before granting the second break. To avoid taking maximum-work-time breaks prematurely, remember that they accumulate work time from the beginning of the route and that work time includes the service time at previously visited depots, orders, and breaks. If this field has a value, TimeWindowStart, TimeWindowEnd, MaxViolationTime, and MaxTravelTimeBetweenBreaks must be null for an analysis to solve successfully. The unit for this field value is specified by the time_units parameter. IsPaid: A Boolean value indicating whether the break is paid or unpaid. A True value indicates that the time spent at the break is included in the route cost computation and overtime determination. A False value indicates otherwise. The default value is True. Sequence: As an input field, this indicates the sequence of the break on its route. This field can contain null values. The input sequence values are positive and unique for each route (shared across renewal depot visits, orders, and breaks) but need not start from 1 or be contiguous. The solver modifies the sequence field. After solving, this field contains the sequence value of the break on its route. Output sequence values for a route are shared across depot visits, orders, and breaks; start from 1 (at the starting depot); and are consecutive.

Parameter: uturn_policy

Data Type: GPString
Display Name UTurn at Junctions
Description: Use this parameter to restrict or permit the service area to make U-turns at junctions. To understand the parameter values, consider for a moment the following terminology: a junction is a point where a street segment ends and potentially connects to one or more other segments; a pseudo-junction is a point where exactly two streets connect to one another; an intersection is a point where three or more streets connect; and a dead-end is where one street segment ends without connecting to another. Given this information, the parameter can have the following values: ALLOW_UTURNS—U-turns are permitted everywhere. Allowing U-turns implies that the vehicle can turn around at any junction and double back on the same street. This is the default value. NO_UTURNS—U-turns are prohibited at all junctions: pseudo-junctions, intersections, and dead-ends. Note, however, that U-turns may be permitted at even when this option is chosen. To prevent U-turns at incidents and facilities, set the CurbApproach field value to prohibit U-turns. ALLOW_DEAD_ENDS_ONLY—U-turns are prohibited at all junctions, except those that have only one connected street feature (a dead end).ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY—U-turns are prohibited at pseudo-junctions where exactly two adjacent streets meet, but U-turns are permitted at intersections and dead ends. This prevents turning around in the middle of the road where one length of road happened to be digitized as two street features. The value you provide for this parameter is ignored unless Travel Mode is set to Custom, which is the default value.

Parameter: route_zones

Data Type: GPFeatureRecordSetLayer
Display Name Route Zones
Description: Delineates work territories for given routes. A route zone is a polygon feature and is used to constrain routes to servicing only those orders that fall within or near the specified area. Here are some examples of when route zones may be useful: Some of your employees don't have the required permits to perform work in certain states or communities. You can create a hard route zone so they only visit orders in areas where they meet the requirements. One of your vehicles breaks down frequently so you want to minimize response time by having it only visit orders that are close to your maintenance garage. You can create a soft or hard route zone to keep the vehicle nearby. When specifying the route zones, you need to set properties for each one, such as its associated route, using attributes. The route zones can be specified with the following attributes: ObjectID: The system-managed ID field. RouteName: The name of the route to which this zone applies. A route zone can have a maximum of one associated route. This field can't contain null values, and it is a foreign key to the Name field in the feature in the routes parameter. IsHardZone: A Boolean value indicating a hard or soft route zone. A True value indicates that the route zone is hard; that is, an order that falls outside the route zone polygon can't be assigned to the route. The default value is 1 (True). A False value (0) indicates that such orders can still be assigned, but the cost of servicing the order is weighted by a function based on the Euclidean distance from the route zone. Basically, this means that as the straight-line distance from the soft zone to the order increases, the likelihood of the order being assigned to the route decreases.

Parameter Type: esriGPParameterTypeOptional

Parameter: route_renewals

Data Type: GPRecordSet
Display Name Route Renewals
Description: Specifies the intermediate depots that routes can visit to reload or unload the cargo they are delivering or picking up. Specifically, a route renewal links a route to a depot. The relationship indicates the route can renew (reload or unload while en route) at the associated depot. Route renewals can be used to model scenarios in which a vehicle picks up a full load of deliveries at the starting depot, services the orders, returns to the depot to renew its load of deliveries, and continues servicing more orders. For example, in propane gas delivery, the vehicle may make several deliveries until its tank is nearly or completely depleted, visit a refueling point, and make more deliveries. Here are a few rules and options to consider when working with route seed points: The reload/unload point, or renewal location, can be different from the start or end depot. Each route can have one or many predetermined renewal locations. A renewal location may be used more than once by a single route. In some cases where there may be several potential renewal locations for a route, the closest available renewal location is chosen by the solver. When specifying the route renewals, you need to set properties for each one, such as the name of the depot where the route renewal can occur, using attributes. The route renewals can be specified with the following attributes: ObjectID: The system-managed ID field. DepotName: The name of the depot where this renewal takes place. This field can't contain a null value and is a foreign key to the Name field in the depots parameter. RouteName: The name of the route to which this renewal applies. This field can't contain a null value and is a foreign key to the Name field in the routes parameter. ServiceTime: The service time for the renewal. This field can contain a null value; a null value indicates zero service time. The unit for this field value is specified by the time_units parameter. The time taken to load a vehicle at a renewal depot may depend on the size of the vehicle and how full or empty the vehicle is. However, the service time for a route renewal is a fixed value and does not take into account the actual load. As such, the renewal service time should be given a value corresponding to a full truckload, an average truckload, or another time estimate of your choice.

Parameter: order_pairs

Data Type: GPRecordSet
Display Name Order Pairs
Description: This parameter pairs pickup and delivery orders so they are serviced by the same route. Sometimes it is required that the pickup and delivery for orders be paired. For example, a courier company might need to have a route pick up a high-priority package from one order and deliver it to another without returning to a depot, or sorting station, to minimize delivery time. These related orders can be assigned to the same route with the appropriate sequence by using order pairs. Moreover, restrictions on how long the package can stay in the vehicle can also be assigned; for example, the package might be a blood sample that has to be transported from the doctor's office to the lab within two hours. When specifying the order pairs, you need to set properties for each one, such as the names of the two orders, using attributes. The order pairs can be specified with the following attributes: ObjectID: The system-managed ID field. FirstOrderName: The name of the first order of the pair. This field is a foreign key to the Name field in the orders parameter. SecondOrderName: The name of the second order of the pair. This field is a foreign key to the name field in the orders parameter. The first order in the pair must be a pickup order; that is, the value for its DeliveryQuantities field is null. The second order in the pair must be a delivery order; that is, the value for its PickupQuantities field is null. The quantity picked up at the first order must agree with the quantity delivered at the second order. As a special case, both orders may have zero quantities for scenarios where capacities are not used. The order quantities are not loaded or unloaded at depots. MaxTransitTime: The maximum transit time for the pair. The transit time is the duration from the departure time of the first order to the arrival time at the second order. This constraint limits the time-on-vehicle, or ride time, between the two orders. When a vehicle is carrying people or perishable goods, the ride time is typically shorter than that of a vehicle carrying packages or nonperishable goods. This field can contain null values; a null value indicates that there is no constraint on the ride time. The unit for this field value is specified by the time_units parameter. Excess transit time (measured with respect to the direct travel time between order pairs) can be tracked and weighted by the solver. Because of this, you can direct the VRP solver to take one of three approaches: Minimize the overall excess transit time, regardless of the increase in travel cost for the fleet. Find a solution that balances overall violation time and travel cost. Ignore the overall excess transit time and, instead, minimize the travel cost for the fleet. By assigning an importance level for the excess_transit_factor parameter, you are in effect choosing one of these three approaches. Regardless of the importance level, the solver will always return an error if the MaxTransitTime value is surpassed.

Parameter Type: esriGPParameterTypeOptional

Parameter: excess_transit_factor

Data Type: GPString
Display Name Excess Transit Factor
Description: Rates the importance of reducing excess transit time of order pairs. Excess transit time is the amount of time exceeding the time required to travel directly between the paired orders. Excess time can be caused by driver breaks or travel to intermediate orders and depots. Listed below are the three values from which you can choose. High—The solver tries to find a solution with the least excess transit time between paired orders at the expense of increasing the overall travel costs. It makes sense to use this setting if you are transporting people between paired orders and you want to shorten their ride time. This is characteristic of taxi services. Medium—This is the default setting. The solver looks for a balance between reducing excess transit time and reducing the overall solution cost. Low—The solver tries to find a solution that minimizes overall solution cost, regardless of excess transit time. This setting is commonly used with courier services. Since couriers transport packages as opposed to people, they don't need to worry about ride time. Using Low allows the couriers to service paired orders in the proper sequence and minimize the overall solution cost.

Description: Specify one or more points to act as temporary restrictions or represent additional time or distance that may be required to travel on the underlying streets. For example, a point barrier can be used to represent a fallen tree along a street or time delay spent at a railroad crossing. The tool imposes a limit of 250 points that can be added as barriers. When specifying the point barriers, you can set properties for each one, such as its name or barrier type, by using attributes. The point barriers can be specified with the following attributes: Name: The name of the barrier. BarrierType: Specifies whether the point barrier restricts travel completely or adds time or distance when it is crossed. The value for this attribute is specified as one of the following integers (use the numeric code, not the name in parentheses): 0 (Restriction)—Prohibits travel through the barrier. The barrier is referred to as a restriction point barrier since it acts as a restriction. 2 (Added Cost)—Traveling through the barrier increases the travel time or distance by the amount specified in the Additional_Time or Additional_Distance field. This barrier type is referred to as an added-cost point barrier. Additional_Time: Indicates how much travel time is added when the barrier is traversed. This field is applicable only for added-cost barriers and only if the measurement units are time based. This field value must be greater than or equal to zero, and its units are the same as those specified in the Measurement Units parameter. Additional_Distance: Indicates how much distance is added when the barrier is traversed. This field is applicable only for added-cost barriers and only if the measurement units are distance based. The field value must be greater than or equal to zero, and its units are the same as those specified in the Measurement Units parameter.

Parameter: line_barriers

Data Type: GPFeatureRecordSetLayer
Display Name Line Barriers
Description: Specify one or more lines that prohibit travel anywhere the lines intersect the streets. For example, a parade or protest that blocks traffic across several street segments can be modeled with a line barrier. A line barrier can also quickly fence off several roads from being traversed, thereby channeling possible routes away from undesirable parts of the street network. The tool imposes a limit on the number of streets you can restrict using the Line Barriers parameter. While there is no limit on the number of lines you can specify as line barriers, the combined number of streets intersected by all the lines cannot exceed 500. When specifying the line barriers, you can set a name property for each one by using the following attribute: Name: The name of the barrier.

Parameter: polygon_barriers

Data Type: GPFeatureRecordSetLayer
Display Name Polygon Barriers
Description: Specify polygons that either completely restrict travel or proportionately scale the time or distance required to travel on the streets intersected by the polygons. The service imposes a limit on the number of streets you can restrict using the Polygon Barriers parameter. While there is no limit on the number of polygons you can specify as the polygon barriers, the combined number of streets intersected by all the polygons should not exceed 2,000. When specifying the polygon barriers, you can set properties for each one, such as its name or barrier type, by using attributes. The polygon barriers can be specified with the following attributes: Name: The name of the barrier. BarrierType: Specifies whether the barrier restricts travel completely or scales the time or distance for traveling through it. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses): 0 (Restriction)—Prohibits traveling through any part of the barrier. The barrier is referred to as a restriction polygon barrier since it prohibits traveling on streets intersected by the barrier. One use of this type of barrier is to model floods covering areas of the street that make traveling on those streets impossible. 1 (Scaled Cost)—Scales the time or distance required to travel the underlying streets by a factor specified using the ScaledTimeFactor or ScaledDistanceFactor field. If the streets are partially covered by the barrier, the travel time or distance is apportioned and then scaled. For example, a factor 0.25 would mean that travel on underlying streets is expected to be four times faster than normal. A factor of 3.0 would mean it is expected to take three times longer than normal to travel on underlying streets. This barrier type is referred to as a scaled-cost polygon barrier. It might be used to model storms that reduce travel speeds in specific regions. ScaledTimeFactor: This is the factor by which the travel time of the streets intersected by the barrier is multiplied. This field is applicable only for scaled-cost barriers and only if the measurement units are time based. The field value must be greater than zero. ScaledDistanceFactor: This is the factor by which the distance of the streets intersected by the barrier is multiplied. This attribute is applicable only for scaled-cost barriers and only if the measurement units are distance based. The attribute value must be greater than zero.

Parameter: use_hierarchy_in_analysis

Data Type: GPBoolean
Display Name Use Hierarchy
Description: Specify whether hierarchy should be used when finding the best routes. Checked (True)—Use hierarchy when finding routes. When hierarchy is used, the tool prefers higher-order streets such as freeways to lower-order streets, such as local roads, and can be used to simulate the driver preference of traveling on freeways instead of local roads even if that means a longer trip. This is especially true when finding routes to faraway locations, because drivers on long-distance trips tend to prefer traveling on freeways where stops, intersections, and turns can be avoided. Using hierarchy is computationally faster, especially for long-distance routes, as the tool has to select the best route from a relatively smaller subset of streets. Unchecked (False)—Do not use hierarchy when finding routes. If hierarchy is not used, the tool considers all the streets and doesn't prefer higher-order streets when finding the route. This is often used when finding short-distance routes within a city. The tool automatically reverts to using hierarchy if the straight-line distance between orders, depots, or orders and depots is greater than 50 miles, even if you have set this parameter to not use hierarchy. The value you provide for this parameter is ignored unless Travel Mode is set to Custom, which is the default value.

Parameter: restrictions

Data Type: GPMultiValue:GPString
Display Name Restrictions
Description: Specify which restrictions should be honored by the tool when finding the best routes. The value you provide for this parameter is ignored unless Travel Mode is set to Custom, which is the default value. A restriction represents a driving preference or requirement. In most cases, restrictions cause roads to be prohibited. For instance, using an Avoid Toll Roads restriction will result in a route that will include toll roads only when it is absolutely required to travel on toll roads in order to visit an incident or a facility. Height Restriction makes it possible to route around any clearances that are lower than the height of your vehicle. If you are carrying corrosive materials on your vehicle, using the Any Hazmat Prohibited restriction prevents hauling the materials along roads where it is marked as illegal to do so. Below is a list of available restrictions and a short description. Some restrictions require an additional value to be specified for their desired use. This value needs to be associated with the restriction name and a specific parameter intended to work with the restriction. You can identify such restrictions if their names appear under the AttributeName column in the Attribute Parameter Values parameter. The ParameterValue field should be specified in the Attribute Parameter Values parameter for the restriction to be correctly used when finding traversable roads. Some restrictions are supported only in certain countries; their availability is stated by region in the list below. Of the restrictions that have limited availability within a region, you can check whether the restriction is available in a particular country by looking at the table in the Country List section of the Data coverage for network analysis services web page. If a country has a value of Yes in the Logistics Attribute column, the restriction with select availability in the region is supported in that country. If you specify restriction names that are not available in the country where your incidents are located, the service ignores the invalid restrictions. The service also ignores restrictions whose Restriction Usage parameter value is between 0 and 1 (see the Attribute Parameter Value parameter). It prohibits all restrictions whose Restriction Usage parameter value is greater than 0. The tool supports the following restrictions:Any Hazmat Prohibited—The results will not include roads where transporting any kind of hazardous material is prohibited. Availability: Select countries in North America and EuropeAvoid Carpool Roads—The results will avoid roads that are designated exclusively for carpool (high-occupancy) vehicles.

Parameter: attribute_parameter_values

Data Type: GPRecordSet
Display Name Attribute Parameter Values
Description: Specify additional values required by some restrictions, such as the weight of a vehicle for Weight Restriction. You can also use the attribute parameter to specify whether any restriction prohibits, avoids, or prefers travel on roads that use the restriction. If the restriction is meant to avoid or prefer roads, you can further specify the degree to which they are avoided or preferred using this parameter. For example, you can choose to never use toll roads, avoid them as much as possible, or even highly prefer them. The value you provide for this parameter is ignored unless Travel Mode is set to Custom, which is the default value. If you specify the Attribute Parameter Values parameter from a feature class, the field names on the feature class must match the fields as described below: AttributeName: Lists the name of the restriction. ParameterName: Lists the name of the parameter associated with the restriction. A restriction can have one or more ParameterName field values based on its intended use. ParameterValue: The value for ParameterName used by the tool when evaluating the restriction. Attribute Parameter Values is dependent on the Restrictions parameter. The ParameterValue field is applicable only if the restriction name is specified as the value for the Restrictions parameter. In Attribute Parameter Values, each restriction (listed as AttributeName) has a ParameterName field value, Restriction Usage, that specifies whether the restriction prohibits, avoids, or prefers travel on the roads associated with the restriction and the degree to which the roads are avoided or preferred. The Restriction Usage ParameterName can be assigned any of the following string values or their equivalent numeric values listed within the parentheses: PROHIBITED (-1)—Travel on the roads using the restriction is completely prohibited. AVOID_HIGH (5)—It is highly unlikely for the tool to include in the route the roads that are associated with the restriction. AVOID_MEDIUM (2)—It is unlikely for the tool to include in the route the roads that are associated with the restriction. AVOID_LOW (1.3)—It is somewhat unlikely for the tool to include in the route the roads that are associated with the restriction. PREFER_LOW (0.8)—It is somewhat likely for the tool to include in the route the roads that are associated with the restriction. PREFER_MEDIUM (0.5)—It is likely for the tool to include in the route the roads that are associated with the restriction. PREFER_HIGH (0.2)—It is highly likely for the tool to include in the route the roads that are associated with the restriction. In most cases, you can use the default value, PROHIBITED, for the Restriction Usage if the restriction is dependent on a vehicle-characteristic such as vehicle height. However, in some cases, the value for Restriction Usage depends on your routing preferences. For example, the Avoid Toll Roads restriction has the default value of AVOID_MEDIUM for the Restriction Usage parameter. This means that when the restriction is used, the tool will try to route around toll roads when it can. AVOID_MEDIUM also indicates how important it is to avoid toll roads when finding the best route; it has a medium priority. Choosing AVOID_LOW would put lower importance on avoiding tolls; choosing AVOID_HIGH instead would give it a higher importance and thus make it more acceptable for the service to generate longer routes to avoid tolls. Choosing PROHIBITED would entirely disallow travel on toll roads, making it impossible for a route to travel on any portion of a toll road. Keep in mind that avoiding or prohibiting toll roads, and thus avoiding toll payments, is the objective for some; in contrast, others prefer to drive on toll roads because avoiding traffic is more valuable to them than the money spent on tolls. In the latter case, you would choose PREFER_LOW, PREFER_MEDIUM, or PREFER_HIGH as the value for Restriction Usage. The higher the preference, the farther the tool will go out of its way to travel on the roads associated with the restriction.

Parameter: populate_route_lines

Data Type: GPBoolean
Display Name Populate Route Lines
Description: Checked (True)—The output routes will have the exact shape of the underlying streets. Unchecked (False)—No shape is generated for the output routes, yet the routes will still contain tabular information about the solution. You won't be able to generate driving directions if route lines aren't created. When the Route Shape parameter is set to True Shape, the generalization of the route shape can be further controlled using the appropriate values for the Route Line Simplification Tolerance parameters. No matter which value you choose for the Route Shape parameter, the best routes are always determined by minimizing the travel along the streets, never using the straight-line distance. This means that only the route shapes are different, not the underlying streets that are searched when finding the route.

Description: Specify by how much you want to simplify the route geometry. The value you provide for this parameter is ignored unless Travel Mode is set to Custom, which is the default value. The tool also ignores this parameter if the populate_route_lines parameter is unchecked (False). Simplification maintains critical points on a route, such as turns at intersections, to define the essential shape of the route and removes other points. The simplification distance you specify is the maximum allowable offset that the simplified line can deviate from the original line. Simplifying a line reduces the number of vertices that are part of the route geometry. This improves the tool execution time.

Parameter: travel_mode

Data Type: GPString
Display Name Travel Mode
Description: Specify the mode of transportation to model in the analysis. Travel modes are managed in ArcGIS Online and can be configured by the administrator of your organization to better reflect your organization's workflows. You need to specify the name of a travel mode supported by your organization. To get a list of supported travel mode names, use the same GIS server connection you used to access this tool, and from the Utilities toolbox, run GetTravelModes. The GetTravelModes tool adds a table, Supported Travel Modes, to the application. Any value in the Travel Mode Name field from the Supported Travel Modes table can be specified as input. You can also specify the value from the Travel Mode Settings field as input. This speeds up the tool execution because the tool does not have to look up the settings based on the travel mode name. The default value, Custom, allows you to configure your own travel mode using the custom travel mode parameters (UTurn at Junctions, Use Hierarchy, Restrictions, Attribute Parameter Values, and Impedance). The default values of the custom travel mode parameters model traveling by car. You may want to choose Custom and set the custom travel mode parameters listed above to model a pedestrian with a fast walking speed or a truck with a given height, weight, and cargo of certain hazardous materials. You may choose to do this to try out different settings to get the analysis results you want. Once you have identified the analysis settings, you should work with your organization's administrator and save these settings as part of a new or existing travel mode so that everyone in your organization can rerun the analysis with the same settings. By choosing Custom, the values you set for the custom travel mode parameters are included in the analysis. Specifying another travel mode, as defined by your organization, causes any values you set for the custom travel mode parameters to be ignored; the tool overrides them with values from your specified travel mode.

Description: Specify the impedance, which is a value that represents the effort or cost of traveling along road segments or on other parts of the transportation network. Travel time is an impedance; a car taking one minute to travel a mile along an empty road is an example of impedance. Travel times can vary by travel mode—a pedestrian may take more than 20 minutes to walk the same mile—so it is important to choose the right impedance for the travel mode you are modeling. Choose from the following impedance values: Drive Time—Models travel times for a car. These travel times are static for each road and don't fluctuate with traffic. Truck Time—Models travel times for a truck. These travel times are static for each road and don't fluctuate with traffic. Walk Time—Models travel times for a pedestrian.

Display Name Time Zone Usage for Time Fields
Description: Specifies the time zone for the input date-time fields supported by the tool. This parameter specifies the time zone for the following fields: TimeWindowStart1, TimeWindowEnd1, TimeWindowStart2, TimeWindowEnd2, InboundArriveTime, and OutboundDepartTime on orders. TimeWindowStart1, TimeWindowEnd1, TimeWindowStart2, and TimeWindowEnd2 on depots. EarliestStartTime and LatestStartTime on routes. TimeWindowStart and TimeWindowEnd on breaks. GEO_LOCAL — The date-time values associated with the orders or depots are in the time zone in which the orders and depots are located. For routes, the date-time values are based on the time zone in which the starting depot for the route is located. If a route does not have a starting depot, all orders and depots across all the routes must be in a single time zone. For breaks, the date-time values are based on the time zone of the routes. For example, if your depot is located in an area that follows eastern standard time and has the first time window values (specified as TimeWindowStart1 and TimeWindowEnd1) of 8 AM and 5 PM, the time window values will be treated as 8:00 a.m. and 5:00 p.m. eastern standard time. UTC — The date-time values associated with the orders or depots are in coordinated universal time (UTC) and are not based on the time zone in which the orders or depots are located. For example, if your depot is located in an area that follows eastern standard time and has the first time window values (specified as TimeWindowStart1 and TimeWindowEnd1) of 8 AM and 5 PM, the time window values will be treated as 12:00 p.m. and 9:00 p.m. eastern standard time assuming eastern standard time is obeying daylight saving time. Specifying the date-time values in UTC is useful if you do not know the time zone in which the orders or depots are located or when you have orders and depots in multiple time zones, and you want all the date-time values to start simultaneously. The UTC option is applicable only when your network dataset defines a time zone attribute. Otherwise, all the date-time values are always treated as GEO_LOCAL.
