Traffic signal control system and method based on edge side online calculation

Abstract

The invention provides a traffic signal control system and method based on edge side online calculation. The system comprises vehicle-mounted terminal equipment, a signal machine and a signal lamp controller, wherein the vehicle-mounted terminal equipment is used for acquiring vehicle information data of an installed vehicle in real time, combining the vehicle information data into a vehicle information data packet and sending the vehicle information data packet to the annunciator; the signal machine is used for calculating and obtaining road condition parameters of each road section of the intersection according to the plurality of collected vehicle information data packets, outputting a current road passing state through a fuzzy comprehensive evaluation model, adjusting a signal timing scheme and sending the signal timing scheme to the signal lamp controller; and the signal lamp controller is used for performing adaptive control on the signal lamp according to the received signal lamp timing scheme. The system can detect and comprehensively analyze the traffic operation state of the intersection in real time; and intersection signal coordination adaptive control is realized.

Description

technical field [0001] The present invention relates to the technical field of traffic state recognition and traffic signal control, in particular, to a traffic signal control system and method based on edge-side online calculation. Background technique [0002] With the continuous development of the social economy, the number of urban vehicles has increased rapidly, and the traffic demand has continued to increase, and it has been saturated for a long time. The main roads in the city are congested and blocked. Reduced operating efficiency and frequent traffic accidents have brought great inconvenience to traffic management and public travel. [0003] An advanced and applicable traffic management system is one of the most effective ways to solve urban traffic congestion, and traffic status recognition and signal control are the core of the traffic management system. Effective organization and coordination will help alleviate the duration of traffic congestion, improve the e...

Problems solved by technology

[0004] At present, the signal control methods mainly include timing control, multi-period control, induction control and background control. The traditional model algorithm sets the threshold according to the change of a certain traffic parameter to optimize the signal, which will cause the system to misjudge the state.
