Abstract
A system for intelligent transport communication includes at least one transmitter, and at least one in-vehicle mobile receiver for use within a mobile road vehicle. The transmitter broadcasts, by wireless communication, dedicated data for each of a plurality of heading directions of the mobile road vehicle, on a corresponding plurality of multiplexed channels. The receiver receives the dedicated data on one of the multiplexed channels that corresponds to an actual heading direction of the mobile road vehicle. A multiple-redundant vehicle heading direction identification system for use within the mobile road vehicle includes a GPS direction identification system, a multiple digital compass system that identifies a heading direction of the mobile road vehicle based on input from multiple digital compasses, and a central processing unit that selects the heading direction produced by the GPS direction identification system only when an output of the GPS direction identification system is healthy.
