摘　　要：科学技术的快速发展使智能交通成为解决交通问题的有效手段。针对交叉口交通流量呈现潮汐性、方向不均衡性的现象,运用交通诱导的思想,提出利用可变进口道解决高峰时段信号交叉口交通拥堵的方法。给出了数据采集的途径和变化车道的条件。采用VMS(可变情报板)及时展示车道变化信息,结合实际,建立交叉口模型,并通过微观交通仿真软件PA-RAMICS丰富的API功能,实现对模型的仿真验证。列出对比评价结果,结果表明进行可变进口道诱导之后,交叉口的服务水平明显提高。The rapid development of science and technology to make intelligent transportation as an effective means to solve traffic problems,for the traffic flow phenomenon of morning and afternoon peak hour traffic and the direction of imbalance at intersection,the thought of traffic guidance is induced,made use of variable approach to solve traffic congestion during peak periods at the signalized intersection,given the way of the data acquisition and the conditions of lanes change.Variable Message Sign（VMS） is used to display the information of lanes change in a timely manner,with the actual the intersection model is established,the same time,with rich API of the microscopic traffic simulation software-paramics to achieve the model simulation,the comparison and evaluation results are presented.The results show that the using of variable approach can significantly improve the intersection level of service.
