Abstract

The invention provides a signal lamp timing evaluation and real-time adjustment method. The method comprises steps: initialization is carried out, and related information is acquired according to an intersection number; a lane group is defined, and under a certain phase, all lanes with the right of way in the same road section are defined as one lane group; a core release lane group under the current phase is found out, and if all phases of a lane have the right of way, the lane is removed from the lane group; a phase key lane is found out; the theoretical minimum period and the maximum period are judged; the saturation of each phase key lane is judged; a penalty function for the period is determined; and a planning function under a non oversaturation phase is determined, a genetic function is called to solve the optimum solution of the planning function, and finally, according to the optimum solution result, based on the period and on the premise of green lamp protection, and the signal lamp is adjusted dynamically.

Description

technical field

[0001] The invention relates to the technical field of public transportation, in particular to a signal light timing evaluation and real-time adjustment method based on a genetic algorithm. Background technique

[0002] In the Intelligent Transportation System (ITS), the control of urban traffic lights is an extremely important part. The rapid increase of urban vehicles and limited road resources make it difficult for traditional traffic light control to achieve satisfactory results. Traditional traffic light control mainly includes fixed-time control and induction control. The fixed-time control method cannot respond to the real-time changing traffic flow.

[0003] Aiming at signal lights at urban intersections, with the goal of reducing the average waiting time of vehicles, and on the premise of taking into account the safety of pedestrians, a real-time timing algorithm for traffic lights is also proposed in the prior art. Real-time regulation. The algo...
