摘要
交通安全已成为城市道路交通亟待解决的重要问题之一。针对以往信号交叉口优化评价指标存在的问题,本文兼顾交叉口的交通安全和通行效率,利用交通冲突技术和Webster优化方法,结合多种微观交通仿真软件,提出了一种安全-效率多目标的交叉口信号控制优化方法。运用VISSIM微观仿真和SSAM软件,从通行效率和安全性等级角度进行交叉口信号评价与优化。实验结果表明,该优化方法使交叉口通行效率提高26.4%,安全性提高22.3%。
Traffic safety has become one of the most important issues in urban road traffic. Aiming at the single evaluation index of the previous signalized intersection optimization,this paper took into account the traffic safety and traffic efficiency at the intersection by using the traffic conflict technology and Webster optimization method. Combining with a variety of microscopic traffic simulation software,this paper proposed a multi-objective intersection signal control optimization method based on safety and efficiency. With the empirical inference of the intersection of Xuehai road of Xianlin avenue,we evaluated and optimized the intersection signal from the perspective of traffic efficiency and safety level in the software of VISSIM microsimulation and SSAM.The experimental results show that the optimization method can effectively improve the traffic efficiency of intersections by 26.4%and improve the safety by 22.3%.
