I'm trying to develop a system to get best path to travel user based on road traffic (congestion level). Functionality of the system should be provide least congested path for traveler given destination from his/her current location.
Note - I'm using OSGeo live 6.5 , Postgresql , MapServer wms services etc. for now.
There are routing libraries like pgroute to get shortest path. Is there such libraries/tool that we can use for above stated development?
