Research on a Delay Model of an Intersection in Nanning City under the Condition of Mixed Traffic

Mixed traffic is one of the typical features of road traffic in China. Especially at intersections, pedestrians, and non-motorized vehicles usually have a substantial effect on the driving environment of motorized vehicles, even causing bottlenecks. A conventional HCM delay model is applicable to the motorized intersections which mainly consist of vehicles. Non-motorized vehicles are not considered in this model. This paper takes Nanning City as a case to improve the intersection delay model by introducing a non-motorized vehicle interference factor γ in the HCM2010 delay model. The main influence factors of γ include the proportion of non-motorized vehicles and the degree of saturation within the intersection. The functional relationship between γ and the two factors are fitted by using SPSS software. Consequently the improved delay model of intersections under the condition of mixed traffic in Nanning City is built. Comparison of numerical calculation results and simulation results show that the average relative error is small enough to verify the usability of the model.
