Research On The Traffic Organization Plan Of Qingshan Road Passing Through The Huancheng Expressway Interchange Reconstruction Project

At present,the length of expressways in China shows a trend of rapid growth,and the traffic flow of expressways also increases day by day.At the same time,due to the limitations of historical conditions,the expressway built in the early stage could not meet the driving needs of the current expressway in terms of both technical standards and service level,nor could it meet the needs of the rapid development of social economy.Especially in the reconstruction and expansion of a large number of highways,frequent traffic congestion phenomenon,greatly reduce the capacity of the highway,and may cause traffic accidents,so the “high speed” changed to “low speed”.Therefore,it is particularly urgent to carry out further research on traffic organization during the reconstruction and expansion of expressway.This article is based on the analysis of domestic and foreign research status,combined with the actual situation during the construction of the Bai Yun section of Qing Shan Road in Gui Yang City,and puts forward the main content of this article.It further clarified the concept of highway reconstruction and expansion,summarized and summarized the highway reconstruction and expansion methods and construction methods,and analyzed the traffic impact and traffic characteristics during the reconstruction and expansion period.Secondly,according to the results of highway traffic characteristics analysis,combining with the highway traffic organization and management measures,in ensuring a smooth flow of traffic during the highway construction and the principle of,develop scientific,efficient and feasible projects of highway traffic during the construction organization plan,including the subgrade pavement,Bridges,interchange,traffic organization scheme and the special circumstances of the emergency response plan.Finally,based on the research results of traffic organization scheme during the reconstruction and expansion of expressway,taking the reconstruction project of Bai Yun section of Qing Shan road in Gui Yang city as an example,the traffic organization scheme and emergency plan during the construction period are determined and evaluated.
