快速路入口匝道控制策略综述

An Overview of Expressway On-ramp Control Strategy

随着城市规模的逐步扩大,机动车保有量和交通需求都有了明显增长,各种交通问题逐渐涌现出来。在众多问题中,日益严重的交通拥堵是各城市发展共同面临的社会问题,其中快速路的堵塞尤为严重。因此,如何通过实施合理的控制措施来缓解快速路交通拥堵,成为当前研究的重点,在众多的快速路交通控制策略中,匝道控制相关的研究较多,取得的效果也较好。本研究重点介绍了快速路入口匝道控制,根据对交通信息反应的区别可将入口匝道控制策略分为静态控制和动态感应控制;根据控制区域的范围将其分为单点控制和协调控制。最后在总结现有匝道控制策略的基础上,对未来的快速路匝道控制策略的研究方向进行了展望。

With the gradual expansion of the scale of the city,the number of motor vehicles and traffic demand have increased significantly.All kinds of traffic problems emerge gradually.Among many problems,increasingly serious traffic congestion is a common social problem in the development of cities,especially the expressway congestion.Therefore,how to alleviate the traffic congestion of expressway by reasonable control measures has become the focus of the current research.Among the many expressway traffic control strategies,there are more researches on ramp control and better results.This study focuses on the on ramp control of expressway,which can be divided into static control and dynamic induction control according to the different responses to traffic information;according to the scope of control area,it can be divided into single point control and coordinated control.Finally,on the basis of summarizing the existing ramp control strategies,it looks forward to the future research direction of expressway ramp control strategies.
