A Counter-Overflow Scheme for Controlling Oversaturated Traffic at Intersections Based on Double Detectors

The paper presents a control scheme of counter-overflow by use of double detectors to alleviate the problem of overflow at intersections with oversaturated traffic. According to the conservation principle, the running status of vehicles at intersections with saturated traffic and the queuing rule of vehicles under traffic congestion, the paper develops a method of determining the installation positions of the overflow identification and queue dissipation detectors. According to the different status of traffic lights at intersections with overflow and its downstream intersection, two counter-overflow schemes—intercept or evacuate are formulated based on minimum green. Finally, a VISSIM simulation is conducted at two adjacent intersections of Anli Road in Beijing to evaluate the proposed control scheme. Results show that the scheme can mildly eliminate traffic overflow, and make the transition from the counter-overflow control phase to the timer control phase smoothly and thus prevents the drastic changes in traffic flow.
