The Bing Maps blog announced that they have revamped their algorithm for determining driving directions.
They went from the "Dijkstra" algorithm as their routing engine to a new one they named "Customizable Route Planning." The new algorithm is twice as fast in calculating driving directions - try it, it does seem incredibly snappy and also offers alternative routes, up to three.
Chris Pendleton from Microsoft said, "for any of our route calculations we’re now processing requests twice as fast as we ever have." "We exposed a feature in the API for alternate routes, so when you’d like to see additional options for the route you can request up to 3 routes in one request using the maxSolutions method,:" Chris added.
