According to the White Paper on the Aged Society of the Cabinet Office in the Heisei 28th year, the proportion of the population aged 65 years or older (the aging rate) in the total population of Japan continues to increase, and in 2060 it is predicted that the aging rate will reach 39.9% , An increase in traffic accidents involving the elderly is also expected. Due to such social background, Hiroshima Prefectural Police Department implemented safe driving seminars for experienced elderly drivers to experience driving safety support vehicles, promoted the promotion of safe driving support vehicles, and the traffic accident in the prefecture Thereby reducing the number of occurrences. In order to further promote the promotion of safe driving support vehicles, it is important to show the effect. In this study, pedestrian injury data by vehicle type and velocity are extracted from traffic accident integrated data stored in Institute for Traffic Accident Research and Data Analysis (ITARDA), and an approximate expression for the relationship between the collision velocity and fatal or serious injury rate by vehicle type causing the pedestrian accident was determined. Then, this approximate expression was applied to a pedestrian fatal accident in Hiroshima Prefecture that occurred in 2017. And the authors estimated the pedestrian injury reduction effect of safe driving support vehicles.
