I want to develop one algorithm which can predict shortest time to be taken to go to a destination from a source in a road network based on traffic congestion data. Consider that I have a server which gives me real time traffic congestion data for all the path segments in a road network. Now I want to develop such an algorithm which can predict time to be taken based on these data. So in short:
time_to_be_taken_from_source_to_destination = function ( traffic_congestion_data ). And 'time_to_be_taken_from_source_to_destination' is proportional to 'traffic_congestion_data' as time increases when traffic_congestion increases.
Are there any such algorithm alraedy developed? Any idea? reference to any algorithm or theory will be appreciated.
