单点交通信号控制系统的优化设计与仿真
Optimize design and simulation of traffic signal control system in isolated intersection
摘要
Abstract
The paper presents a fuzzy control system structure for an urban junction adopting fixed phase orders and multiphase. The traffic flows in the next cycle may be estimated, and the maximum time of green light is adjusted dynamically. Each phase time is determined according to traffic urgency degree of current phase and next phase. Using genetic algorithm to modify fuzzy membership functions, the system can change its membership functions adaptively to an optimal setting in different traffic situations. A simulation experiment at intersection is performed and the performance is measured with average vehicle delays through the intersection. Simulations result shows that the fuzzy control system can effectively decrease the average delaying time, improve traffic average velocity in the intersection and is superior to the conventional method.关键词
