ABSTRACT:
A communication system for displaying route specific messages onboard a plurality of mass transit vehicles operating along designated routes within a geographical area serviced by a cellular telephone network includes a transmitter connectable to any telephone in the telephone system, the transmitter capable of transmitting messages to any other addressable telephone number in the system, and a cellular based visual communication unit mounted onboard each of the vehicles, each of the units having an addressable telephone number. The transmitter and each cellular based visual communication unit cooperatively assure that the contents of the route specific messages transmitted from the transmitter via the cellular telephone system to the respective vehicle are received, stored and subsequently displayed in an error-free condition, regardless of whether or not the vehicles are mobile or stationary.
