摘　　要：在城市道路网中,路网优化的主要内容是信号协调,而信号协调又以干线协调为主。文章阐述了Vistro的路网优化原理及相关参数配置方法,介绍了Vistro应用于城市道路干线协调的相关方法理论,并以唐山市北新道为例,使用遗传算法对交叉口信号控制方案进行干线协调优化分析,得到了优化后的效果图。结果证明,Vistro在城市道路干线协调中具有较好的实用性和高效性。In the urban road network,the main content of road network optimization is the signal coordination,while the signal coordination is mainly focused on the trunk road coordination. This article de-scribed the Vistro road network optimization theory and related parameter configuration methods,and introduced the related method and theory of applying the Vistro in urban trunk road coordination,then with Beixin Road in Tangshan City as an example,it used the genetic algorithms to conduct the trunk road coordination optimization analysis for intersection signal control programs,and obtained the opti-mized renderings. The results proved that Vistro has better practicability and efficiency in urban trunk road coordination.
