ARTERIAL TRAFFIC LIGHT OPTIMIZATION AND CONTROL METHOD AND DEVICE

摘要

An arterial traffic light optimization and control method and device, the method comprising: based on the pre-acquired traffic flow entering and exiting an arterial road from each third-class road between adjacent junctions of the arterial road, correcting vehicle speed and traffic flow on the arterial road between adjacent junctions, calculating the correlation between adjacent junctions, and dividing the junctions on the arterial road into subsystems according to the correlation; calculating the cycle of each subsystem and the green ratio of each junction to obtain a green wave control parameter; and utilizing the obtained green wave control parameter to conduct green wave control on the subsystems having a correlation greater than or equal to a preset value. The method and device divide all the junctions on an urban traffic arterial road into subsystems for processing according to the correlation between the junctions, so as to achieve a green wave control effect, thus improving the green ratio of a traffic intersection, and enabling most vehicles to pass through a green wave band.
