Abstract
In this paper, two methods for practical verification and complementation of speed data stored in EDR are presented. Both methods are based on analyses of actual collision accidents and can be performed in parallel with conventional accident analysis procedure. One of the two methods uses video footage stored in vehicle-mounted camera (black box) to estimate the speed of vehicles. The other method is for performing optimal analysis based on vehicle collision model built in the range of rigid body dynamics. Through analyses of black box footage from actual collision accidents, it was confirmed that the estimated speed matched the data stored in EDR with high accuracy. Additionally, by using actual collision cases, the practicality of vehicle collision model-based speed estimation method was validated. In cases where video footage is not available, optimization method based on rigid body collision model can be used together with EDR data.
