Research on tourist city traffic signal intelligent control method

摘要

A traffic lights control method was proposed based on the phase interrupt control strategy. The algorithm refers to computer interrupt event handling method and determines whether to extend passage time according to the phase green light time when the interrupt is triggered by traffic flow. Based on vehicle traffic ability function and average vehicle delay function, the method was optimized. And simulation study was carried out on a planar orthogonal crossroads in Taian city of Shandong province in china. Simulation results confirmed that the effectiveness of the method and the average vehicle delay time was reduced 24.9%. This indicates that the method can effectively improve transport efficiency, which has a very important significance for tourism city to relieve the traffic pressure.
