Reconstructing accidents by simulation for developing active safety systems

This paper describes the development of a method to reconstruct accident scenarios by simulation as a means of helping to develop more effective active safety systems through quantitatively estimating the potential real-world accident reduction benefit of a system. This method enhances the validity of benefit estimation results by defining the road environment as well as the characteristics of the vehicle, system, and driver behavior based only on actual data. The validity of the method was also ensured by increasing the number of parameters considered and analyzing the dependency relationships between parameters, so that the simulation results reproduce the same characteristics as actual accident data. The robustness of this method was verified by inputting accident data from other regions around the world and confirming its ability to simulate accident scenarios in these regions. As a result, a method capable of simulating crossing pedestrian accidents, lane departure accidents, and rear-end accidents was developed using accident data from Japan, the U.S., and Europe. This method helps to identify the effectiveness of active safety systems in different accident scenarios and the type of support that is necessary to reduce accidents further. This information can then be fed back into active safety system development.
