You can also use the attribute parameter to specify whether any restriction prohibits, avoids, or prefers\ntravel on roads that use the restriction. If the restriction is\nmeant to avoid or prefer roads, you can further specify the degree\nto which they are avoided or preferred using this\nparameter. For example, you can choose to never use toll roads, avoid them as much as possible, or even highly prefer them. The values you provide for this parameter are ignored unless Travel Mode is set to Custom. If you specify the Attribute Parameter Values parameter from a\nfeature 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\nrestriction. A restriction can have one or more ParameterName field\nvalues based on its intended use. ParameterValue: The value for ParameterName used by the tool\nwhen evaluating the restriction. Attribute Parameter Values is dependent on the\nRestrictions parameter. The ParameterValue field is applicable only\nif the restriction name is specified as the value for the\nRestrictions parameter. In Attribute Parameter Values, each\nrestriction (listed as AttributeName) has a ParameterName field\nvalue, Restriction Usage, that specifies whether the restriction\nprohibits, avoids, or prefers travel on the roads associated with\nthe restriction and the degree to which the roads are avoided or\npreferred. The Restriction Usage ParameterName can be assigned any of\nthe following string values or their equivalent numeric values\nlisted within the parentheses: PROHIBITED (-1)\u2014Travel on the roads using the restriction is completely\nprohibited. AVOID_HIGH (5)\u2014It\nis highly unlikely for the tool to include in the route the roads\nthat are associated with the restriction. AVOID_MEDIUM (2)\u2014It\nis unlikely for the tool to include in the route the roads that are\nassociated with the restriction. AVOID_LOW (1.3)\u2014It\nis somewhat unlikely for the tool to include in the route the roads\nthat are associated with the restriction. PREFER_LOW (0.8)\u2014It\nis somewhat likely for the tool to include in the route the roads\nthat are associated with the restriction. PREFER_MEDIUM (0.5)\u2014It is likely for the tool to include in the route the roads that\nare associated with the restriction. PREFER_HIGH (0.2)\u2014It is highly likely for the tool to include in the route the roads\nthat are associated with the restriction. In most cases, you can use the default value, PROHIBITED,\nfor the Restriction Usage if the restriction is dependent on a\nvehicle-characteristic such as vehicle height. However, in some\ncases, the value for Restriction Usage depends on your routing\npreferences. For example, the Avoid Toll Roads restriction has the\ndefault value of AVOID_MEDIUM for the Restriction Usage parameter.\nThis means that when the restriction is used, the tool will try to\nroute around toll roads when it can. AVOID_MEDIUM also indicates\nhow important it is to avoid toll roads when finding the best\nroute; it has a medium priority. Choosing AVOID_LOW would put lower\nimportance on avoiding tolls; choosing AVOID_HIGH instead would\ngive it a higher importance and thus make it more acceptable for\nthe service to generate longer routes to avoid tolls. Choosing\nPROHIBITED would entirely disallow travel on toll roads, making it\nimpossible for a route to travel on any portion of a toll road.\nKeep in mind that avoiding or prohibiting toll roads, and thus\navoiding toll payments, is the objective for some; in contrast,\nothers prefer to drive on toll roads because avoiding traffic is\nmore valuable to them than the money spent on tolls. In the latter\ncase, you would choose PREFER_LOW, PREFER_MEDIUM, or PREFER_HIGH as\nthe value for Restriction Usage.
