ABSTRACT:
A method, a system, and an apparatus are provided for wireless communication of a traffic signal over a network. A message comprising data related to the traffic signal is received. Thereafter, the forwardability of the message is detemined. If forwardable, the message is forwarded. The validity of the message is checked and if found to be valid, information in the data is communicated to a vehicle controller. The message is discarded, if it is found to be invalid.
