A development of a Traffic Simulator for Safety Evaluation

- Reproduction of Traffic Accidents and Evaluation of Safety Systems -

Abstract

We are developing a traffic simulator called STREET, which evaluate effectiveness to reduce accidents by safety systems. To evaluate safety systems, however, we have to be able to faithfully reproduce traffic accidents that are caused by interactive events between vehicles and between vehicles and pedestrians. In this method, we have constructed the driver model of normal driving behavior, and driver model which simulate driver's error in cognition, decision-making and operation. In this paper, we describe a method of reproducing traffic accidents. In addition, we talk about evaluating the ratio of accidents with/without active safety systems.
