ABSTRACT:
In one general aspect, a method for signaling traffic flow information includes monitoring a status for a traffic restrictor, generating a wireless signal indicative of the status of the traffic restrictor, and communicating the wireless signal to a receiver. In another general aspect, a wireless receiver includes a wireless interface and a processor. The wireless interface receives a wireless signal indicative of a status of a traffic restrictor. The processor determines a portion of a route for a vehicle based upon the status of the traffic restrictor.
