| 摘 要： | 为提高城市主干道交通通行能力,通过建立多交叉口信号配时的优化模型,对主干道单点交叉口配时优化和相邻交叉口之间相位差的线性协调进行研究,并利用Matlab软件对模型进行求解。最后以福建省莆田市荔城南大道与国道G324、荔园西路两个相邻交叉口为优化对象,并利用Synchro软件对优化结果进行仿真。结果表明,优化方案使交叉口服务水平提高一个等级,两个交叉口总延迟时间降低20.1%。

| Abstract: | In order to improve the urban road traffic ability, this paper establishes the optimization model of the signal timing of several intersections. It studies the optimization of the single intersection signal timing and the linear coordination of phase offset between adjacent intersections. And it uses Matlab to solve the model. The paper takes Licheng South road of Putian which intersects with National road G324 and Liyuan West road as an example. The results of optimization are simulated by Synchro. It is proven that the method proposed visually improves the service level of the intersection road with a grade, and reduces the total delay time of the two intersections by 20.1 %. |
