In order to promote business in commercial districts and create a safer and more secure and friendly environment for the pedestrians in downtown, Hangzhou Government has proposed that Yan'an Road and Huansha Road be reconverted to two-way traffic in central business districts (CBD). Prior to the reconversion it is necessary to estimate traffic impacts for different flow configuration scenarios. This can provide a basis for the design and plan of traffic organization. This paper presents an approach based on VISSIM to estimate the traffic impacts of different flow configuration scenarios. The existing configuration scenario was simulated using the Static Decision of routes with network entry volume, traffic composition and turning percentage at intersections. The future configuration scenarios were simulated using the Dynamic Assignment of Routes with network entry volume, traffic composition and origin-destination (OD) matrices. The proposed approach was used to estimate traffic impacts of Yan’an Road and Huansha Road converted to two-way traffic. Results indicated that speed reduced and intersection delays and stops increased in the two-way configurations. The findings suggest that the two-way configuration scenario could be desirable with careful design and planning.
