The GetRouteCostMatrix service calculates the travel time and distances between an array of start and end locations and returns the route that is either the fastest or the shortest. The result determines the total time and distance of the individual routes (the route costs). For example if you input four start points and four end points, a total of 16 routes will be calculated.

Note: Response from REST service will be in JSON format and the geometry returned will be in GeoJSON format
