集成ETC系统的城市快速路常发性交通拥堵管理策略

Management Strategy for Recurrent Traffic Congestion of Urban Expressway Integrated with ETC System

分析城市快速路常发性交通拥堵特点,基于ETC(电子不停车收费)系统功能和匝道控制原理,提出了快速路ETC匝道控制和匝道出入口OD流量分析模型。通过判断分析关键匝道出入口及其常发性拥堵的不同原因,提出相应的拥堵管理策略,为快速路的常发拥堵管理及匝道控制提供参考。

The article analyzes the characteristics of recurrent expressway congestion, and presents the expressway ETC ramp control and ramp access OD flow analysis model based on ETC(Electronic Toll Collection) system function and ramp control principle. According to the determination and analysis of the key ramp accesses and the different causes of recurrent congestion, the article proposes the corresponding congestion management strategies, which can be referenced for the recurrent congestion management and ramp control of the similar expressways.
