ABSTRACT:
A method and system for providing travel guidance for transportation vehicles traveling on a highway system that comprises highway transceivers (HTs) with limited range placed at selected intervals along the highway. Each transportation vehicle has an automobile transceiver (AT) for receiving and transmitting information using a communication protocol. The HTs have a limited transmission range. The AT may be programmed to selectively present information received from the HTs to a passenger in an automobile. The ATs may also receive information from other transportation vehicles equipped with an AT. The HTs may receive information from all of the transceivers or other transmitters, for example, a GPS satellite transmitter. The HTs may also transmit information to traffic signal units about numbers of vehicles in its transmission pattern.
