An Optimal Control Method for Traffic Lights at Urban Road Intersections

Abstract

The invention discloses an optimal control method for traffic lights at urban road intersections, which includes (1) dismantling and determining eight kinds of traffic phases on four bayonets according to the time and space characteristics of actual vehicle passage at the intersection; (2) determining the eight kinds of The phase compatibility table is established for the passing phase, and it is determined that any two passing phases are compatible if they do not conflict; (3) According to the phase compatibility table, the driving safety calculation formula is obtained, and then 12 kinds of compatible phase combinations are obtained; ( 4) Steps such as precalculating and forming the original phase sequence series table and the transformed phase sequence series table corresponding to the original phase sequence in the original phase sequence series table according to the pairwise compatible phase combination. The present invention provides an optimal control method for traffic lights at urban road intersections, which breaks through the limitations of traditional traffic strategies, overcomes the inertial thinking in the industry, optimizes the traffic strategy at traffic intersections, and greatly relieves the traffic pressure at traffic intersections. The traffic efficiency of vehicles is improved.

Description

technical field [0001] The invention belongs to the field of traffic signal control, in particular to an optimal control method for traffic lights at city road intersections. Background technique [0002] With the development of society, the number of vehicles in each city is gradually increasing, which makes the degree of vehicle congestion higher and higher. In order to solve the problem of vehicle congestion and alleviate the traffic pressure in the city, the traffic management department has issued various regulations, and many companies have also designed a variety of traffic methods to increase the traffic rate of intersections, but the final results are not satisfactory. In order to alleviate the traffic pressure, our company also designed a patented product with the application number "201721832135.X" and the name "an intelligent traffic command device". The disadvantages of the patented product have also caused the effect of the setting of the patented product to a...
