Abstract

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.

Description

technical field [0001] The invention relates to the field of urban traffic road control, in particular to a method and device for optimal control of traffic arterial signal lights. Background technique [0002] At present, road congestion has become a prominent problem faced by urban traffic. Many experts in the industry focus on ITS (Intelligent Transportation), hoping to alleviate urban congestion through ITS. The green wave coordination system is an important means for ITS to improve traffic efficiency and relieve congestion. [0003] The green wave coordination system is one of the core systems of ITS. Green wave control of urban intersection signals refers to the coordinated control of traffic signals at several consecutive intersections in a main road. The purpose is to make the vehicles driving at the intersections of the coordinated control of the main road pass through the intersections in the coordinated control system without encountering red lights or rarely en...
