Abstract
A system and method is disclosed for communicating data and transmitting information between roadside infrastructure units regarding vehicle data. In some embodiments, the roadside infrastructure units have one or more communication nodes equipped with a wireless transceiver configured to communicate wirelessly with a vehicle such as a dedicated short-range communication (DSRC) or cellular system. Each communication node can also wirelessly communicate with one or more of the other remaining communication nodes in, for example, a mesh network. One of the communication nodes can establish a connection with the vehicle via DSRC, obtain vehicle-specific data, and transmit at least a portion of this vehicle-specific data to one or more other communication nodes in other roadside infrastructure units. The roadside units can change operation state (e.g., illuminate) in response to receive the vehicle-specific data indicating the vehicle approaching that roadside unit.
