Abstract

The invention provides a signal light timing evaluation and real-time adjustment method, including: initialization, obtaining relevant information through the intersection number; defining lane groups, wherein in a certain phase, all lanes with the right of way on the same road section are defined as a lane group; Find out the core clearing lane group of the current phase, if: the lane has the right of way in all phases, remove the lane from the lane group; find out the key lane of the phase; determine the theoretical minimum cycle and maximum cycle; determine each Phase-critical lane saturation; determine the penalty function for the period; determine the planning function under the non-oversaturated phase, and call the genetic function to solve the optimal solution of the planning function, and finally according to the optimal solution result, based on the cycle and the green light protection premise , dynamically adjust the signal light.

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...
