A system and method for regulating the flow of traffic at a roadway intersection having one or more traffic signals by positioning a processor in the vicinity of the intersection to store cycle times of the traffic flow directions, mounting an RFID reader in the vicinity of each traffic signal in communication with the processor, interrogating with the RFID reader an RFID tag on each RFID-tagged vehicle at the roadway intersection to count the number of RFID-tagged vehicles present in each traffic flow direction at the roadway intersection, calculating an unused time slice of the cycle time for a first traffic flow direction at the intersection; reducing the cycle time for the first traffic flow direction in accordance with the unused time slice; and, increasing the cycle time for a second traffic flow direction at the intersection in accordance with the unused time slice.
