It then calls ◦ the geo location API’s and gets the current location of the vehicle from the location manager. ◦ the mapping API’s to calculate the distance to the crash location and displays it. ◦ the rerouting API’s from the mapping service rerouting by avoiding the crash location. Note: the MapQuest open data API’s are used.
