Abstract
An exemplary vehicular apparatus includes a radio frequency receiver adapted for receipt of signals transmitted from intelligent street sins. A computer receives recovered 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 and identifies a first field containing a first value that represents a predetermined type of vehicle for which the information contained in the other fields is relevant. The computer compares the first value with a stored value in memory to determine if the information contained in the other fields is relevant to the vehicle and recovers the information contained in the other fields if it is determined that the other fields are relevant to the vehicle.
