ABSTRACT

With the acceleration of China's urbanization, investment in transportation infrastructure is increasing. In this paper, the traffic influence area of the construction period is divided into three levels, and the design method of traffic organization based on the three-level dissolving method is proposed. In the first-level traffic impact zone, peripheral traffic guidance was designed based on the research of the drivers’ detour route selections. In the second-level traffic impact zone, regional traffic diversion was designed through macroscopic road network modeling using OD estimation in Trans CAD software. In the third-level traffic impact zone, node traffic organization was designed according to microscopic node simulating evaluation with VISSM software. Last, this paper chose the Wuhan East Lake High-Tech Development Zone, which is surfing a period with large scale construction as an example. Specific traffic organization plans were made to verify the feasibility of the three-level ease method in the traffic organization during large scale construction period.
