Abstract:The second undersea tunnel in Jiaozhou Bay of Qingdao connects the old Huangdao with the east coast urban, and is of great significance in strengthening the traffic links between the east and west banks of Jiaozhou Bay, which has been started to construct. In order to meet the demand for traffic relief at the Huangdao end of the tunnel and improve the traffic operation efficiency, the traffic connection scheme of the skeleton road networks at the end of Huangdao of the second tunnel is studied. Based on the analysis of the current situation and planning conditions of the Huangdao area, the travel demand across the sea is predicted. And the traffic impact of the tunnel on the regional road network is analyzed. The suggestions for the improvement and optimization of the Huangdao terminal connection road and the construction timing are proposed. Finally, the overall scheme for upgrading Huaihe Road, Shugang Elevated Road and Huanghe Road is studied, which aims to provide the reference for the subsequent road construction.
