The function of traffic impedance has been one of the key topics in traffic distribution and safety studies. There are two parts included in urban arterial road traffic impedance. One is on road sections, while the other is on intersections. Traditionally, road sections and intersections were considered as independent road facilities in the analysis of traffic impedance. However, the method is not useful for impedance analysis of the whole road network and has negative effects on the accuracy of traffic distribution. The paper summarizes the factors affecting the traffic impedance on urban arterial roads and signalized intersections. Based on the analysis of the data of urban road sections and intersections, a comprehensive model on urban traffic impedance is proposed using a linear regression method. Finally, the specific model is determined on the basis of data collection.
