城市错位交叉口交通改善措施研究——以赣州河套老城

Study on Traffic Improvement Measures at Urban Staggered Intersections in Hetao Old Town of Ganzhou

摘要:

通过研究总结错位交叉口运行特点，提出错位交叉口四大优化改善策略，降低错位交叉口对路网通行效能的负面影响。赣州河套老城区红旗大道沿线为典型的错位交叉口，同时运用左转右置渠化和双向绿波协调控制，并通过VISSIM 仿真软件对方案进行仿真评价，综合改善措施能有效缓解交叉口交通流的延误。

Abstract:

By studying and summarizing the operating characteristics of staggered intersections, four types of optimization and improvement strategies for the staggered intersections are proposed to reduce the negative impact of staggered intersections on the traffic efficiency of the road network. The typical staggered intersections are along Hongqi Avenue in the Hetao Old Town in Ganzhou City, and at the same time, the coordinated control of left-turn right-set channelization and two-way green wave is applied. And the simulation and evaluation of the scheme are carried out through VISSIM simulation software. The comprehensive improvement measures can effectively alleviate the delays of traffic flow at the intersections.
