Abstract
The present invention is a method and an apparatus for end-to-end travel time estimation using dynamic traffic data. In one embodiment, a method for estimating a fastest route between a first point in a transportation network and a second point in the transportation network includes receiving static data relating to static characteristics of a first zone and a second zone in the transportation network. In addition, real-time data relating to real-time traffic conditions in the first zone is also received. The static and real-time data is processed in accordance with at least one fine-grained load-generation technique to generate a first load for the first zone, and the static data is generated in accordance with at least one coarse-grained load-generation technique to generate a second load for the second zone. These first and second loads are then combined, converted to travel times, and scaled to facilitate the identification of a best or fastest route.
