Abstract： Being in a period of rapid urban development intertwined with fast motorization in China, the country experiences different level of safety between urban roadways and non-urban highways. Focusing on the characteristics of urban traffic safety, this paper summarizes the characteristics of urban road traffic safety at different time periods based on the accident data and traffic citations from 2007 to 2016, which takes into account the crash temporal and spatial characteristic. By analyzing the causes of these accidents' characteristics, the paper discusses the relationship between road safety and roadway design, travel modes, and travel behaviors. Finally, the paper proposes improving traffic safety techniques aiming at high accident risk factors and event such as timing, intersection, resurging non-motorized traffic accident, the rising electric-bike accident, high frequency of truck accidents at night, high fatal and injury pedestrian accidents, and increasing accident risk for elderly.
