RoutingService

<RoutingService>NetRoad or TrackRoad or Bing</RoutingService>

The routing service is used to get time, distance and directions from location to location.  Default is NetRoad.  Use Bing if you need accurate times between each location.  Bing can be slower than calling the native NetRoad routing service.  Also, the Bing service costs slighty more credits due to the cost of the service.  The usage of NetRoad is recommended over other services.
