Rear-End Road Crash Characteristics Analysis Based on Chinese In-Depth Crash Study Data

摘要

Road crashes are still a big problem for traffic safety. Rear end crashes are one important crash type researchers are trying to mitigate. China's In-depth crash study collects and analyzes road crashes in order to provide data support for new technologies research. This paper uses data collected by the China In-depth crash study to analyze rear end road crash characteristics in China using three parts: passenger car-to-passenger car rear end crashes, passenger car-to-truck rear end crashes, and truck-to-truck rear end crashes. Results found that driving at night and fatigued driving are main factors for truck rear end crashes. Use of safety belts was found to decrease an occupant's injury severity. Underrun protection devices and small overlap collision testing are necessary in China.
