南昌市典型干线公路与城市干道衔接点交通优化

Traffic Optimization at the Typical Intersection between a Trunk Highway and an Urban Arterial Roadway in Nanchang

由于干线公路与城市干道交通功能上的差异性,导致干线公路与城市干道衔接点易产生交通拥堵.以南昌市干线公路与城市干道典型交叉口作为研究对象,通过对交叉口交通流构成、信号控制及交通渠划等进行分析,提出衔接点交通优化方案,最后通过Vissim仿真检验改善方案的有效性,为今后指导国省干线公路与城市干道衔接提供参考.

Due to the difference in the traffic function between trunk highways and urban arterial roadways, it is easy to cause the traffic congestion at the intersection of the two. This paper conducts an empirical study of the typical intersection of a trunk highway and an urban arterial roadway in Nanchang, and proposes an intersection traffic optimization scheme based on the analysis of traffic flow composition, signal control and channelization plans. Finally, the scheme is validated using VISSIM to provide a reference for the design guidelines of the intersection between a trunk highway and an urban arterial roadway.
