1. A system for providing traffic information to a plurality of mobile users connected to a network, comprising:
- (a) a plurality of mobile user stations, each mobile user station being associated with a display, and a communicating device to allow each of said mobile user stations to send and receive signals;
(b) a computer system interconnected with another communicating device and a network, said computer system being capable of sending and receiving signals to and from said mobile user stations;
(c) said computer system including a traffic information database, said traffic information database containing data representative of traffic at a plurality of locations;
(d) at least one of said mobile user stations providing a request to said computer system for traffic information together with a signal associated with a respective geographic location of said one of said mobile user stations, and in response thereto, said computer system updating said traffic information database based on said geographic location of said one of said mobile user stations and providing to said one of said mobile user stations information representative of selected portions of said traffic information database based on said respective geographic location of said one of said mobile user stations; and
(e) said one of said mobile user stations displaying graphically on said display information representative of selected portions of said traffic information database.

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.
