Study on traffic organization design of expressways with heavy traffic flow during occupying-road construction

In order to further optimize the traffic organization designing process and methods during the road-occupying construction of expressways with heavy traffic flow, based on the in-depth analysis of the basic traffic operation conditions of expressways with heavy traffic flow, this paper put forward the general principles of traffic organization during the road-occupying construction. The general process of the design work and the specific methods of each stage are defined. Finally, by taking the Ningbo-Taizhou-Wenzhou Expressway as an example, a specific case was analyzed. The research results of this paper can provide reference for the research and formulation of traffic organization schemes during the road-occupying construction of expressways with heavy traffic flow.
