Abstract

The invention provides a dynamic signal lamp assessment method based on a genetic algorithm, and the method comprises the steps: carrying out the initialization, and obtaining related information through an intersection number; defining a lane group, wherein all lanes with the passing right at one phase at the same segment are defined as one lane group; finding a core permission lane group at a current phase, wherein the lane is removed from the lane group if the lane has the passing right at all phases; finding the key lane at the phase; determining a theoretical minimum period and a theoretical maximum period; determining the saturation of the lane at each phase; determining a punishment function for the period; determining a programming function at a non-oversaturation phase, carrying out the call of a genetic function to solve an optimal solution of the programming function. The invention also proposes a dynamic signal lamp assessment system based on the genetic algorithm.

Description

technical field [0001] The invention relates to the technical field of public transportation, in particular to a genetic algorithm-based dynamic signal light evaluation method and system. 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 algorithm includes two...
