Abstract

Combined with the example of the Baoxia Hub interworking project design of Yunxi–Baoxia Section of Shiyan via Zhenping–Wuxi Expressway in the mountainous hilly area of western Hubei, this paper introduced the main forms of composite interworking design under the condition of the dislocated intersection of mountainous expressways, discussed the applicable conditions and characteristics of each scheme, and analyzed the advantages and disadvantages of each scheme. The results show that by choosing a reasonable composite interworking form, the normal traffic flow of the intersecting expressway is guaranteed, and the straight heading capacity of the main line under the condition of a dislocated intersection is guaranteed. In addition, the safe and efficient mutual conversion of the traffic flow between the expressways is achieved.
