Based on the vehicle collision dynamics model, this study provided an optimized algorithm with vehicle final location and other related information for the tire marks. When the tire marks simulation results fit the real one well, the state of vehicle can be understood as the real state in the accident. Based on above, the vehicle velocity and direction are decided. According to the velocity and direction of the vehicle, the complete accident process can be simulated. With the help of the Pc-Crash software, the method has been applied in typical collision accident cases analysis. The reconstruction results will provide the scientific and numerical references for vehicle collision accidents analyzing and appraising.展开更多

Among them, 435 persons died (mortality, (21.3)%) and 1 605 were injured. The economic losses were over 170 million yuan RMB. The accidents caused by human factors accounted for (84.9)% (vehicle drivers accounting for (79.2)%), which mainly included improper measures ((20.4)%), steering failure ((17.7)%), insufficient longitudinal space ((15.9)%), over-speed drive ((12.5)%), fatigue drive ((6.4)%), loading violation ((5.9)%) and careless drive ((6.3)%). Mechanical troubles and other factors took up (15.1)%. There existed obvious uneven distribution among various regions. Jiaxing and Shaoxing were the sections with high incidence of accidents. The accidents mostly happened at 12:00-18:00, but the causing-dead ones most concentrated at 0:00-6:00. The main victims were young and middle-aged people (accounting for (72.3)%), but accident-stricken children and elderly persons (over 70 years old) took up higher mortalities ((30.2)% and (40.7)%, respectively). Conclusions: The number of expressway traffic accidents and the economic losses are increasing year by year, with obvious uneven distribution at different places, different time and under different weather conditions. To reduce the accident frequency, it is important to strengthen the enforcement of traffic regulation, to balance the system of ”person-vehicle-road”, and to improve the safety consciousness of people.展开更多
