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.
