Research Abstract	Drivers have no method to evaluate the objective risk when passing the blind intersection. Thus, they drive a vehicle with using their subjective risk evaluation based on their driving experiences. In order to decrease such a collision, the method is needed for drivers to recognize the precise risk of broadside collision. In this study, a mathematical broadside collision model between two vehicles was developed using a simple two driver models on each road in order to evaluate the objective driving risk. This collision model can predict the possibility of broadside collision (POC) and pre-crash kinetic energy (PKE) as the index of collision damage between the vehicles. The experiments to calculate POC and PKE with the broadside collision model by using Monte Carlo simulation were conducted under various traffic conditions. As a result, it was found that vehicle speed, distance between the edge of the road and the car, traffic density, and shape of the intersection affect POC and PKE.
