重庆四公里立交至江南立交拥堵改造分析

Analysis on the Congestion Transformation of Chongqing Sigongli Interchange to Jiangnan Interchange

文章主要探讨重庆四公里立交至江南立交拥堵改造设计,分析立交范围内交通运行特征及交通拥堵分布,深入剖析立交拥堵成因,结合分析结论将两座立交及相关设施视为统一整体进行交通组织设计,针对性地提出多项立交改造措施,同时依靠VISSIM交通仿真软件对现状和改造方案进行模拟及评价,为四公里立交至江南立交改造提供技术支持,也为城市立交拥堵改造提供参考。

This article mainly discusses the congestion transformation design of Chongqing Sigongli Interchange to Jiangnan Interchange,analyzes the traffic characteristics and traffic congestion distribution within the scope of the interchange,and deeply analyzes the causes of interchange congestion.Combined with the analysis conclusions,these two interchanges and related facilities are treated as a unified whole for the traffic organization design,and it proposes a number of targeted interchange transformation measures.At the same time,it simulates and evaluates the current situation and transformation plan based on VISSIM traffic simulation software,thus providing the technical support for Sigongli Interchange to Jiangnan Interchange and also providing the reference for urban interchange congestion transformation.
