For detection of magnetic induction coil section only able to show the status of vehicle information,proposed intersection signal control to design a sensor-based electronic license plate.The design is by setting the intersection of reader interaction with vehicles equipped with active RFID tags,get the continuity of information flow and detect vehicle road section on specific driving condition.To detect vehicles queuing length of the evaluation criteria,select the greatest demand for the green light to run as the next phase of the phase.Showed improved control strategy can achieve real-time traffic signal control effectively at high saturation intersection,improving the utilization of urban intersection comparative analysis by simulation.
