Abstract
A method and system to estimate vehicle traffic conditions for use in a vehicle navigation system. The system includes a cellular network which receives position data from a plurality of GPS enabled cellular telephones. A processor in the cellular network is programmed to estimate the traffic conditions or density of traffic on at least one road link based upon the received position data while a transmitter at the base station then transmits that estimated traffic condition to automotive vehicles containing navigation systems. A processor in the navigation system then utilizes the estimated traffic conditions for route and/or arrival time calculations.
