Research Of Traffic Organization Design Method For New Interchange Project Of Operating Expressway

With the continuous development and improvement of expressway network in our country,more and more new expressways are crossing and connecting with the existing expressways through the hub-building interaction.The New Interchange Project on the operating expressway is carried out under the environment of a passing expressway.The implementation of the project ensures the safety of the construction of the project,at the same time,it also minimizes the impact on the operating highway and ensures the safety of the road.Compared with other sections of the operating expressway,the road conditions and traffic conditions in the construction area of the intersection project have changed significantly,which has a profound impact on the traffic flow characteristics of the construction area.The traffic organization design involved in this paper is one of the important tasks to ensure the smooth development of the new junction interchange project and the smooth road safety.This paper studies the traffic organization design of the junction Interchange Project Based on the Yinghua junction interchange completed during 2016-2018 in the G4 Expressway.Firstly,the paper analyses the scheme of the new junction interchange project of operating expressway,summarizes and summarizes the key points of the traffic organization design of the interchange project.Secondly,the road characteristic analysis,traffic characteristic parameter analysis and temporary traffic safety facilities layout method in the construction area of the crossing project are studied.Finally,taking the Shengping junction interchange project currently being implemented in the G4 Expressway as an example,this paper further discusses the design points and methods of the traffic organization of the interchange project,which provides the implementation of the Shengping junction interchange and promotes the smooth development of the project.At the same time,it further analyses and verifies the new junction interchange project proposed in this paper.Design methods and ideas.
