The list of network attribute names to be accumulated with the analysis, i.e., which attributes should be returned as part of the response. The default is as defined in the specific routing network layer used in your RouteTask. You can specify any attributes names listed in the Service Directory under "Network Dataset -> Network Attributes" as "Usage Type: esriNAUTCost".

A set of attribute parameter values that can be parameterized to determine which network elements can be used by a vehicle. The parameter holding a vehicle charactersitic is compared to a value coming from a descriptor attribute to determine whether or not a network element is traversible. For example, a parameterized restriction attribute can compare the height of your vehicle with a descriptor attribute that holds the clearance under overpasses through tunnels. If the vehicles height is greater than the clearance, the edge is restricted. Parameterized cost attributes that can reference other cost attributes and scale them, can also be used. This is useful when inclement weather like ice, fog or heavy rain, descends on the study area and hinders normal flow of traffic. By having a parameter already outfitted on a cost attribute, travel-time expectations and traversible network paths can be adjusted with respect to changes in traffic speeds.

The language to be used when computing directions. The default is as defined in the specific routing network layer used in your RouteTask. By default, NAServer gets installed with en_US only - it is up to the server administrator to add additional languages.

The length units to use when computing directions. The default is as defined in the specific routing network layer used in your RouteTask. Possible values are "esriFeet", "esriKilometers", "esriMeters", "esriMiles", "esriNauticalMiles" and "esriYards".

The name of network attribute to use for the drive time when computing directions. The default is as defined in the specific routing network layer used in your RouteTask.

If true, avoid network elements restricted by barriers or due to restrictions specified in restrictionAttributes.

The default value is false.

If true, the solver will optimize the order of the stops in the route (while taking into account preserveFirstStop and preserveLastStop if they were set to true). The default is as defined in the specific routing network layer used in your RouteTask.

When false, the solve operation will fail if at least one of the stops specified cannot be located or reached. If true, invalid locations are ignored and route(s) will be returned as long as there are at least two valid stops that have been connected by a route. If multiple routes are processed in a single request a valid result will be returned as long as least one route is built. The list of routes that cannot be solved is included in RouteSolveResult.messages property.

The network attribute name to be used as the impedance attribute in analysis. The default is as defined in the specific routing network layer used in your RouteTask. You can specify any attributes names listed in the Service Directory under "Network Dataset -> Network Attributes" as "Usage Type: esriNAUTCost". You can also specify a value of "none" to indicate that no network attributes should be used for impedance. If you specify an empty string, it will use the default of the service.

For example, set impedanceAttribute="Time" for quickest route and impedanceAttribute="Length" for shortest drive. Assuming the service has those two esriNAUTCost attributes.

The precision of the output geometry after generalization. If 0, no generalization of output geometry is performed. If present and positive, it represents the MaximumAllowableOffset parameter - generalization is performed according to IPolycurve.Generalize.

The units of the output geometry precision.

The default value is esriUnknownUnits.

The type of output lines to be generated in the result. The default is as defined in the specific routing network layer used in your RouteTask. Possible values are "esriNAOutputLineNone" (no line at all), "esriNAOutputLineStraight" (a straight line from start to end) and "esriNAOutputLineTrueShape".

If true, the solver should keep the first stop fixed in the sequence (even when findBestSequence is true). Only applicable if findBestSequence is true. The default is as defined in the specific routing network layer used in your RouteTask.

If true, the solver should keep the last stop fixed in the sequence (even when findBestSequence is true). Only applicable if findBestSequence is true. The default is as defined in the specific routing network layer used in your RouteTask.

The list of network attribute names to be used as restrictions with the analysis. The default is as defined in the specific routing network layer used in your RouteTask. Possible values are listed in the Service Directory under "Network Dataset -> Network Attributes". You can also specify a value of "none" to indicate that no network attributes should be used as restrictions. If you specify an empty array, it will default to the default of the service.

     myRouteParams.restrictionAttributes = ["OneWay"];

     myRouteParams.restrictionAttributes = ["none"];

Specifies how U-turns should be handled. The default is as defined in the specific routing network layer used in your RouteTask. Possible values are "esriNFSBAllowBacktrack", "esriNFSBAtDeadEndsOnly", "esriNFSBNoBacktrack" and "esriNFSBAtDeadEndsAndIntersections".
