1. A method of identifying congestion comprising:
- monitoring traffic conditions using off call tracking data relating to cellular mobile communication devices carried in vehicles along an off call path;
determining when an off call path crossing time of the call path exceeds a threshold;
when the off call path crossing time exceeds the threshold, obtaining traffic data from probe vehicles on roads corresponding to the off call path;
analyzing the traffic data to determine the location of the congestion along the off call path and to determine various degrees of severity of the congestion and to determine physical extent of the congestion; and
providing at least one of the location, the various degrees of severity, and the physical extend of the congestion along the off call path as an output of a traffic information system.

Abstract
A method of identifying congestion comprising the steps of monitoring traffic conditions using off call tracking data relating to cellular mobile communication devices carried in vehicles along an off call path and determining when an off call path crossing time of the call path exceeds a threshold. When the off call path crossing time exceeds the threshold, obtaining traffic data from probe vehicles on roads corresponding to the off call path, and analyzing the traffic data to determine the location of the congestion along the off call path.
