1. An apparatus adapted for use in a vehicle comprising:

  • a radio frequency receiver adapted for receipt of signals transmitted from intelligent street signs;

    a computer, coupled to the receiver, receives a packet of digital data from the receiver, where the digital data represents information contained in the signals received by the receiver;

    the computer parses the digital data into separate fields where each field contains values representing information related to the corresponding street sign;

    the computer identifying a first field containing a first value where the first value defines a predetermined type of vehicle for which the information contained in the other fields is relevant;

    the computer comparing the first value with a stored value in memory of the computer to determine if the information contained in the other fields is relevant to the vehicle;

    the computer recovering the information contained in the other fields if the comparison of the first value with the stored value determined the other fields to be relevant to the vehicle.
