Calling Get RoadSpeeds

RoadSpeedsRequest request = new RoadSpeedsRequest();
  request.Header = new  RequestHeader() { DataVersion =  DataVersion.ToString(), RequestType = "GetRoadSpeeds" };
  // construct body - NJ roads
  request.Body = new RoadSpeedsRequestBody();
  request.Body.Jurisdiction = "NJ";
  request.Body.Vehicle = VehicleType.Auto;

  // Create the authentication and authorization header
  AuthHeader soapHeader =  GenerateAuthHeader( APIName);

  // Create the service client
  ServiceClient service = new ServiceClient();

  // Call API
  RoadSpeedsResponse response = service.GetRoadSpeeds(soapHeader, request);
