1. A traffic surveillance system comprising:

  • a first sensor positioned to sense vehicular traffic in a predetermined first field;

    a first local traffic processor coupled to the first sensor for identifying vehicles within the field of the first sensor by periodically sampling the first sensor and extracting vehicle locations and identification information;

    a second sensor positioned to sense vehicular traffic in a second predetermined field where said second predetermined field is separated from said first predetermined field;

    a second local traffic processor coupled to the second sensor for identifying vehicles within the field of the second sensor by periodically sampling the second sensor and extracting vehicle locations and identification information; and

    a wide area traffic flow processor coupled to each local traffic processor for receiving the vehicle location and identification information from each local traffic processor and tracking the identified vehicles;

    wherein the wide area traffic flow processor utilizes a predictor algorithm to predict each identified vehicle'"'"'s location, and utilizes the vehicle location and identification information to correct the predictor model thereby functioning to monitor traffic consisting of all the identified vehicles.
