Embodiment Construction

[0039] In the following, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the drawings in the embodiments of the invention.

[0040] Such as figure 1 , The present invention provides a traffic signal timing method based on collaborative optimization, including the following steps:

[0041] Step 1. Conduct relevance evaluation of adjacent intersections in the road network;

[0042] Step 1.1. The traffic information center collects historical traffic volume of each road and the distance between adjacent intersections according to the road network information in the geographic information database. The geographic information database of the traffic information center includes vehicle information tables, real-time traffic information tables, and For the Q value table of each cooperative control area, the road network information includes road network topology and road length;

[0043] The data of the Q value table in...

Abstract

The invention provides a traffic signal time assignment method based on collaborative optimization. The relevance between intersections is determined according to actual distribution of comprehensivesignal lamps and traffic flow, a signal collaborative control area based on SCAN cluster partition is determined, connected intersections with stronger relevance are gathered in the same cluster, andby means of a Boltzmann selection strategy, adaptive collaborative control is performed after regional learning intellectual bodies are subjected to sufficient experience accumulation until the signalcontrol ends, and passing rate of vehicles in a small-area range is increased, so that the traffic efficiency of the overall road network is improved.

Description

Technical field [0001] The invention relates to the technical field of urban traffic signal control, in particular to a traffic signal timing method based on collaborative optimization. Background technique [0002] Due to the increasing number of vehicles in the city, the road traffic environment is deteriorating day by day, traffic congestion occurs frequently, and intersections become the bottleneck of traffic congestion. Urban traffic congestion greatly takes up people’s travel time and reduces travel efficiency. Fuel consumption, traffic pollution and other issues make the traffic problem an urgent problem in the development of modern cities. Therefore, reasonable control of urban intersection signals has become a hot topic in the research of transportation departments. [0003] The adaptive control method of traffic signal is controlled in real time by analyzing the traffic flow at the intersection. With the continuous in-depth understanding of the traffic flow law between ...
