Cellular based traffic sensor system
First Claim
1. A method for providing vehicular traffic information, comprising the steps of:
- monitoring signals on control and voice channels of a cellular telephone system by means of a plurality of receivers tuneable to a desired control or voice channel;
analyzing the signals monitored on the control and voice channels of the cellular telephone system for recognition of an emergency, the steps of analyzing the signals including;
detecting a preselected signal within the signals monitored on the control channels;
monitoring a voice channel for a preselected signal for key words indicating an emergency;
classifying the emergency in response to the detected key words; and
generating vehicular traffic reports in response to analysis of the signals monitored on the control and voice channels.

Abstract
A method for providing emergency 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 for emergency conditions. Data from these transmissions is extracted and analyzed for emergencies according to a statistical model and derived vehicle geolocating information to generate emergency 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 emergency conditions existing along major thoroughfares may be determined.
