Comparison of Different Means to Determine Postcrash Velocity in a Real-World Vehicle-Pedestrian Accident

In road traffic collisions, the majority of victims are pedestrians in many countries. Claims in vehicle-pedestrian collision often have to be settled in court. The most concern of vehicle crash accident reconstruction is to retrieve the postcrash velocity. In this study, the conventional methods and Event Data Recorder (EDR) were applied to determine postcrash velocity in a real-word vehicle-pedestrian accident. The study showed limitation and scientific rationality of the conventional methods, and the EDR data of this accident was verified at the same time.
