Abstract:Abstract: With the accelerated growth of motor vehicle ownership in Wuhan, the traffic becomes increasingly heavier at the certain nodes of the network of urban skeleton roads, where the congestion usually occurs in the morning and evening peak periods. Based on the two traffic nodes of Zhuye mountain and Moshui Lake interchange engineering, this paper introduces the characteristics and difficulties of the widening reconstruction, and thereafter analyzes the feasibility of the reconstruction projects. At last, this paper proposes an applicable overall scheme of widening reconstruction, which can provide reference for related projects.
