Abstract: Objective To explore the relationship between pedestrian traffic accidents and the type of vehicles and summarize the characteristics. Methods Ninety cases of pedestrian traffic accidents were reviewed, and the relationship between the types of vehicles and the injuries （site, feature and severity） were analyzed. Results Different impact injuries were caused by different types of vehicles. The primary sites of the impact injuries depended on the body posture and the height of protruding parts of the front when the accident happened. The injury characteristics were related to the size, direction of acting force and contact surface. Conclusion The analysis of position, feature, and severity of pedestrian injury can determine the type of injury vehicle.
