Traffic accidents are major concern even though technologies such as ITS are being developed. It is important to predict where and how traffic accidents might occur, and to investigate how to prevent traffic accidents. Traffic simulators that have the function of simulating traffic accidents can help users to predict them. Our goal is to make a traffic simulator that can reproduce traffic accident and can be used for wide area simulation. In this paper, we developed new traffic accident models and implemented them to an existing traffic simulator. We considered drivers' errors and classified them into 4 patterns for modeling traffic accidents. We reproduce 5 traffic accidents in a realistic situation by modeling traffic accidents depending on the environment surrounding the driver. To compare the number of accidents in the real world and simulation, we have done sensitivity analysis with changing the error rates.
