The Influence of Bohai Strait Tunnel Project on Freight Transportation System in Bohai Economic Rim

摘要

This paper studied the influence of Bohai Strait Tunnel project on freight transportation system in Bohai Economic Rim by considering different transportation routes and modes. The model of modified Negative Exponent Network Flow Assignment was introduced in the paper. The market share of three transport routes in 2050, including Tonghua-Yantai, Chifeng-Yantai and Dalian-Yantai, was predicted. Results indicated that Bohai Strait Tunnel can shorten transportation distance and reduce transportation cost, and the two transportation modes of highway transportation and railway transportation through tunnel are economical and have larger market share better than that of the other transportation modes. It is very necessary to construct a transoceanic tunnel across the Bohai Strait.
