Urban road intersection traffic light optimal control method

Abstract

The invention discloses an urban road intersection traffic light optimal control method. The method comprises the following steps of: (1) disassembling and determining eight passing phases on four bayonets according to the real vehicle traffic space-time characteristics of an intersection; (2) establishing a phase compatibility table for the eight passing phases, and determining that any two passing phases are compatible if no conflict is generated; (3) acquiring a traffic safety calculation formula according to the phase compatibility table so as to obtain 12 pairwise compatible phase combinations; and (4) forming an original phase sequence series table and a transformation phase sequence series table corresponding to the original phase sequence in the original phase sequence series tablethrough pre-calculation according to the pairwise compatible phase combinations. The urban road intersection traffic light optimal control method provided by the invention breaks through the limitation of a traditional traffic passing strategy, overcomes the inertial thinking in the industry, optimizes the passing strategy of the traffic intersection, greatly relieves the passing pressure of thetraffic intersection, and improves the passing efficiency of vehicles.

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...
