Research on Road Network Capacity under Mixed Traffic in Nanning City

Previous research on urban road network capacity involves only motor vehicles and does not consider non-motor vehicles on the road network. Since there still are large numbers of non-motor vehicles in most cities in China, this study proposes a model to calculate road network capacity under mixed traffic conditions using the time and space resources consumption (TSRC) model. Differences between motor vehicles and non-motorized vehicles are taken into account, and total road network resources under mixed traffic conditions are obtained accordingly. Taking Nanning City as a case study, the capacity of the urban road network and the corresponding maximum ownership numbers of motor vehicles and non-motor vehicles in Nanning city are given. Results show that the mixed road network capacity in consideration of non-motor vehicles can be used to compare with vehicle ownership and to evaluate the operating situation of the urban road network more effectively.
