ABSTRACT:
Characterizing traffic conditions by analyzing operational data taken from a wireless communication network to generate traffic information. Location estimates can be made based on processing the operational data. This location can be combined with computerized street maps to measure the time it takes to get from one geographic area to another. By aggregating and analyzing anonymous data from thousands of devices, the present invention is able to determine real-time and historical travel times and velocities between cities, intersections and along specific routes.
