A Boolean value specifying whether to calculate the route using traffic information.
The default value is false, which means the route will be calculated without considering traffic information.
If the property UseTraffic is set to true and the VERouteOptions.RouteOptimize property is set to VERouteOptimize.MimimizeTime, then the route calculation engine considers available traffic information and changes the route accordingly to minimize the route time.
If the property UseTraffic is set to true and the VERouteOptions.RouteOptimize property is set to VERouteOptimize.MimimizeDistance, then the route will not change, but available traffic information will be included in the itinerary.
Available traffic information is returned only if the VERouteOptions.RouteMode Property is set to VERouteMode.Driving. If the UseTraffic property is set to true and the VERouteOptions.RouteMode property is set to VERouteMode.Walking, then an empty VERoute object is returned. An empty VERoute object has no itinerary and the VERoute.Distance Property and VERoute.Time Property are 0.
