First Claim
1. A system for intelligent transport communication, comprising:
- at least one transmitter; and
at least one in-vehicle mobile receiver for use within a mobile road vehicle;
wherein the at least one transmitter is programmed to broadcast simultaneously, by wireless communication, a plurality of different sets of dedicated data for each of a corresponding plurality of heading directions of the mobile road vehicle, on a corresponding plurality of multiplexed channels; and
the receiver is programmed to tune selectively to one of the multiplexed channels that corresponds to an actual heading direction of the mobile road vehicle, and to receive the dedicated data on the one of the multiplexed channels that corresponds to the actual heading direction of the mobile road vehicle.

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.

14. A multiple-redundant vehicle heading direction identification system, comprising:
-
a GPS direction identification system for use within a mobile road vehicle; and a multiple digital compass system for use within the mobile road vehicle programmed to identify a heading direction of the mobile road vehicle based on input from multiple digital compasses; and a central processing unit programmed to select the heading direction produced by the GPS direction identification system when an output of the GPS direction identification system is healthy during travel of the mobile road vehicle, and to select the heading direction produced by the multiple digital compass system when an output of the GPS direction identification system lacks signal integrity during travel of the mobile road vehicle.

15. An integrated multifunction unit for intelligent transport communication, for use within a mobile road vehicle, comprising:
-
a receiver capable of multiple channel reception, for receiving road-side-to-vehicle wireless communications from at least one road-side transmitter on one of a plurality of multiplexed channels having a corresponding plurality of different sets of simultaneously broadcast dedicated data for each of a corresponding plurality of heading directions of the mobile road vehicle; a vehicle heading direction identification system; and a central processing unit programmed to cause the receiver to tune selectively to at least one of the multiplexed channels that corresponds to an actual heading direction of the mobile road vehicle, and to receive dedicated data on the at least one of the multiplexed channels, the at least one of the multiplexed channels corresponding to the actual heading direction of the mobile road vehicle. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. An integrated multifunction unit, further for use within a first mobile road vehicle, comprising:
-
a receiver; a central processing unit; and an in-vehicle transmitter programmed for communication with the receiver of an integrated multifunction unit of a second mobile road vehicle, the in-vehicle transmitter being programmed to re-transmit, in relay fashion, a message received by the receiver of the first mobile road vehicle from a transmitter of an integrated multifunction unit of a third mobile road vehicle; the central processing unit being programmed to cause the message transmitted in relay fashion to be transmitted in a lowest available time slot for retransmission, in a frequency of the message received from the third mobile road vehicle plus a frequency increment of one.

26. An integrated multifunction unit for intelligent transport communication, for use within a mobile road vehicle, comprising:
-
a subscriber identity module for use within the mobile road vehicle; a mobile communication system, for use within the mobile road vehicle, for receiving a coded message from a vehicle registering authority; and
for sending intermittent messages to a licensing office number identified in the subscriber identity module;a central processing unit, for use within the mobile road vehicle, programmed to cause the subscriber identity module, in response to receipt by the subscriber identity module of a coded message from the vehicle registering authority, to send the intermittent messages to the licensing office number identified in the subscriber identity module; the intermittent messages containing vehicle coordinates and vehicle details based on information in the subscriber identity module.
