ABSTRACT:
A method and apparatus for providing vehicular traffic information using presently existing cellular telephone system technology. Traffic sensors monitor the control and voice channel transmissions of cellular units within a cellular telephone system. Data from these transmissions is extracted and analyzed according to a statistical model and derived vehicle geolocating information to generate vehicular traffic information that is transmitted to a central control center. By combining the information from all of the traffic sensors and each individual cell within a cellular telephone system, a picture of the traffic conditions existing along major thoroughfares may be determined.
