  • Patent number: 6666411
    Abstract: A vehicle control system and method in which a plurality of beacon tags are disposed along a length of a track for a predetermine number of blocks. The beacon tags each provide information pertaining its location. Each vehicle that passes along the track has a tag reader that solicits information from the beacon tags and a transmitter that transmits the solicited information, as well as vehicle identification information for the transmitting vehicle, to a wayside control unit. The wayside control unit receives the transmitted position information and vehicle identification information and in turn transmits a single broadcast of information pertaining to each of the blocks of the predetermined number of blocks.
