The evaluation of an occupant protection device in traffic accidents is necessary to improve its device. Impact severity of a vehicle is one of the most important factors that is related with the injury severity of occupants, however, it was difficult to count for it in case of using statistical accident data because no direct data is available. In this paper, it is shown firstly that the delta-V is a good predictor to evaluate the occupant severity and secondly based on the conservation of the momentum, pseudo delta-V is introduced to evaluate the impact severity in case of applying statistical accident data. New passenger car model introduced into the Japanese market in October 1998 should comply with the regulation which requires occupant injury criteria in side collisions. It was revealed that the regression model that included the pseudo delta V was better than the model without it. The results of the regression analysis show that the number of fatal or seriously injured occupants in vehicles which comply with the occupant protection requirement is decreased more than the former vehicles.
