Route Request Time out

Question

Hi,

can anyone suggest me over these condition....

                                                  1. i have 2000 OR more Points(Locations) from database

                                                   2. i m passing the each location from 2000 Points to the method having  RouteRequest object.

                                             OBJECTIVE: trying to achieve the location for each point(which is passed from database) on the nearest Road.

          GETTING EXCEPTION :The HTTP request to 'http://dev.virtualearth.net/webservices/v1/RouteService/RouteService.svc' has exceeded the allotted timeout. The time allotted to this operation may have been a portion of a longer timeout.

//calling the function to add pushpin for nearest road location

   foreach (Location item in _elementsLocationsInCircle2)
            {
                    GetLocationOnTheNearestRoad(item);
            }

Answer 1

Are you passing these in a loop or something? Or are you just manually passing in one point at a time? It looks like you are just trying to geocode. Note the start and end points must be different. If you want the nearest point on the road then use the geocoding method, there is no need to use the routing service. The geocoding service will be much faster than the routing service and give you the same information you are looking for. Going a step further I highly recommend using the REST geocoding service as it will be significantly faster and more accurate than the SOAP services. The SOAP services should be avoided for all new development. Take a look at this document for using the REST services in .NET: http://rbrundritt.wordpress.com/2012/01/06/bing-maps-rest-service-net-libraries/

Also, you should be using the GetCrednetials method on the Map's Credentials provider so that you create a session key. A session key will mark these requests as non-billable. The way you are currently doing it every request is a billable transaction against your account.

Answer 2

yes m passing these in a loop

      foreach (Location item in _elementsLocations) { GetLocationOnTheNearestRoad(item); }

...............................................

in Geocoding how can i get the Location on the nearest for a point which is not on the road.is it possible????if yes plz sugget me...

using route services it is taking 40 seconds for 250 points.

Answer 3

The geocoding service (in REST) returns a value called the UsageType, this will say routable for points which are on the road. Also, all addresses have points on the road. This is usually also the default coordinate. Basically you are over complicating things. If you just use the default functionality of the Geocoding service and the standard coordinates returned you would be getting the points that are on the road.

Answer 4

//increasing time interval for routerequest
                TimeSpan ts=new TimeSpan(2,30,0);
                binding.ReceiveTimeout = ts;
                binding.OpenTimeout = ts;
                binding.SendTimeout = ts;
