With the advancement of urban renewal, the supply of existing road resources is no longer balanced with new traffic demand, leading to severe traffic congestion and safety issues in urban renewal areas. This article firstly analyzes the traffic load capacity of the road network in urban renewal areas by using the macroscopic fundamental diagram (MFD) theory, a traffic status and volume correlation model is constructed to identify the optimal traffic volume for the road network. Secondly, a VISSIM traffic simulation model is constructed to evaluated the traffic status of the intersections at the regional boundary by using average delay, average queue length, average number of stops and service level four indexes. Finally, a field study in Xiaozhai District Xi’an is carried out to evaluate the feasibility of the proposed method. Results show that the MFD method can effectively describe traffic status and volume relationship of urban renewal areas, under the optimal traffic flow load, the intersections and road links at the study area are able to reach a good system performance. This study can provide technical support for traffic management in urban renewal areas.
