A system and method for computing routing on a road network are described. One embodiment includes pre-processing routing data for one or more environmental profiles integrated into a hierarchy, dynamically adding links to the hierarchy in response to real-time data on traffic conditions, and cluster-routing to approximate routing travel costs based on realtime traffic data A further embodiment includes a) identifying one or more portions of a road network as being more preferable than normal based on real-time data, b) expressing the one or more portions of the road network as a sequence of locations comprising a uniquely identifiable path, c) using the sequence of locations comprising a uniquely identifiable path to add one or more links to an already constructed hierarchical network of roads, and d) enabling a pathfinding algorithm to adjust to the real-time data. |
