Problems solved by technology

[0005] The third key of the system to reduce the impact of non-motor vehicles on the control efficiency of plane perception signals is to accurately determine whether the current traffic state is low peak, flat peak, or peak. , or peak control strategy, the biggest problem in this method is that the determined control strategy is different from the actual traffic conditions, which leads to poor control effect of signal lights

Abstract

The invention discloses a method and device for reducing the impact on the control efficiency of a plane sensing signal from a motor vehicle. The method and system employs a control scheme of obtaining the numbers of parking times of a motor vehicle in a first direction and a second direction during red lights, and adjusting the signal lights according to the number of waiting times in the two directions during red lights. When the largest numbers of waiting times in the first and second directions during red lights are zero, a judgment that the number of motor vehicles is very small can be made, and the motor vehicles can pass an intersection without waiting for the green lights. Meanwhile, when the signal lights in the first direction are green, motor vehicles may pass through the intersection or may not, and the control key point of the signal light control can be adjusted to take the safe passing of non-motor vehicles through the intersection as the basic condition, i.e., controlling the green light time in the first direction, and guaranteeing that the last non-motor vehicle of a queue waiting for the passing passes through a stop line. Moreover, the full-red time of signal lights of the intersection is prolonged to the moment when the last non-motor vehicle passes through the intersection.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and system for reducing the influence of non-motor vehicles on the control efficiency of plane sensing signals. Background technique [0002] Improving the efficiency of the intersection signal control system, reducing the time lost for green lights, reducing the number of motor vehicle parking, shortening the parking time, and at the same time ensuring the safety of non-motor vehicles passing through the intersection has become a topic of concern, which has attracted a lot of attention from experts and scholars at home and abroad. According to the current research, due to the limitation of the technical level of detectors of motor vehicles and non-motor vehicles, reducing the impact of non-motor vehicle traffic on the control efficiency of plane perception signals has encountered a bottleneck. [0003] One of the key issues in the system to reduce the...
