Research on the Design of Access Road in Old City Reconstruction

In order to improve the traffic safety and efficiency of new access roads in old city reconstruction, it is necessary to do research on site selection, layout design, and management of access road. By integrated analysis of multi-level road traffic operation, this paper determines the service level of access road using equivalent traffic capacity replacing intersection capacity as the representative value of road traffic capacity, and in according to the relationship of equivalent capacity and intersection spacing, back calculation of the optional areas of access roads is, which replaces the design method aimed at meeting the demands of the functional areas of intersection. Finally, according to this design idea, we use the road traffic simulation system to simulate the design of access road in the reconstruction of Qi county HeBi city Henan province. The results show that this method satisfies the road network service level and maximizes the system traffic capacity on the basis of traffic safety.
