Road traffic accidents increase dramatically because of the rapid increase in number of cars. A number of complicated factors including vehicle factors, road factors and human factors contribute to the risk of traffic accidents. Especially, the shape and design of vehicles, which are not suitable for the road structure, cause driver visibility problems at the time of driving, for example, the interference with the rearview visibility. This study analyzed the car accidents based on two scenarios of parking and roads after obtaining 68 rear-end car accident data of domestic and foreign countries. Factors influencing the vehicle rearview visibility were classified into eight sub-factors containing tailgate glass and other 7 factors. The cause of the rear-end accidents were investigated by classifying into vehicle-, factor- and scenario-specific categories. Factor-specific rear-end accidental rate was obtained by group analyses of factors influencing the vehicle rearview visibility and categories causing the rear-end accidents(F(2,5)=8.257, p<0.05). The study including vehicle-specific categories demonstrated that SUV showed the highest cause of the rear-end accidents due to two factors, Tailgate glass during parking and O/S mirror on the road driving. The methodology of future experiment and evaluation could be available from studying the factor design considering the vehicle rearview visibility. This study may contribute to providing valuable information for planning the vehicle design and meeting consumers demands.
