Analysis on the Causes of Congestion in Wenjiachang Hub and Research on the Renovation Scheme of Relieving Congestion and Keeping Smooth
摘要
Abstract
Wenjiachang hub,as a traffic conversion node between Chengdu—Wenjiang—Qionglai Expressway and Chengdu Ring Expressway,had serious daily congestion.Based on the evaluation of the traffic operation characteristics of the road section for daily traffic volume during the Spring Festival,the reasons for the congestion of the Wenjiachang hub were analyzed.The result shows that,the congestion is caused due to insufficient service level of the main line expressway,imbalance of the number of lanes,non-standard setting of the variable speed lane,piers in the lane,and lack of sight distance.This paper puts forward the design principles and ideas of the renovation scheme for relieving congestion and keeping smooth,optimizes the schemes for the main line,interchange ramp and confluence end design of Chengdu—Wenjiang—Qionglai Expressway in Wenjiachang hub,and compares and selects the interchange scheme of Wenjiachang hub satisfying the function of relieving congestion and keeping smooth.关键词
