DC CAFCFirst Claim
1. A system for providing traffic information to a plurality of mobile users connected to a network, comprising:
- (a) a plurality of traffic monitors, each said traffic monitor comprising at least a detector and a transmitter, said detector providing a signal including data representative of vehicular movement and said transmitter transmitting said signals;
(b) a receiver, remotely located from said transmitter, that receives said signals transmitted by said traffic monitors; and
(c) a computer system interconnected with said receiver and said network;
(d) a mobile user station connected to a global positioning system receiver, a display, and a communicating device; and
(e) said computer system, in response to a request for traffic information from one of said mobile user stations, providing in response thereto to said one of said mobile user stations traffic information representative of said signals transmitted by said traffic monitors;
(f) wherein said traffic information transmitted by said computer system is displayed graphically on said display; and
(g) wherein said computer system has a map database, and said computer system, in response to said request for information, transmits map information representative of a portion of said map database, and said map information representative of said map database is displayed graphically together with said traffic information.

Abstract
A system for providing traffic information to a plurality of mobile users connected to a network. The system comprises a plurality of traffic monitors, each comprising at least a traffic detector and a transmitter, the traffic detector generating a signal in response to vehicular traffic and the transmitter transmitting the signal. A receiver receives the signals from the traffic monitors. A computer system is connected to the receiver and is further connected to the network. The computer system in response to a request signal received from one of the users transmits in response thereto information representative of the signals transmitted by the traffic monitoring units. Alternative systems for gathering traffic information are disclosed.
