This study clarified the features of fatal truck–pedestrian and truck–cyclist accidents by a comparison with sedans. Fatal accident data from the Japanese Institute Traffic Accident Research and Data Analysis (ITARDA) database were analyzed for the years 2012 ~ 2016. The trucks were classified into three categories: heavy-, medium-, and light-duty. All three categories had higher percentages of pedestrians as fatal collision partners as opposed to cyclists. Every truck category had significantly higher percentages of pedestrian fatalities due to daytime right turns than sedans. Heavy-duty trucks had significantly higher percentages of cyclist fatalities due to daytime and nighttime left turns than sedans. These results show that the design specifications for new sensing technology to avoid collisions with pedestrians and cyclists should differ among vehicle types. The knowledge obtained in this study will be useful to develop new technology or systems that are effective in dangerous situations between trucks and pedestrians or cyclists.

This study attempts to clarify the characteristics of light-duty truck collision accidents involving pedestrians during right-turn maneuvers by analyzing actual pedestrian accident data in Japan. Evidence differences were observed between the daytime and nighttime. The number of injured and fatal pedestrians during the day was larger than that during the night. The rate of vehicle travel velocity ≤ 10 km/h in the daytime (47.0 %) was significantly higher than that in the nighttime (39.2 %), whereas the rate of vehicle travel velocity ≤ 20 km/h in the nighttime (52.7 %) was significantly higher than that in the daytime (46.9 %). The highest rate in the daytime was presented for the age group of 13 ~ 64 years in minor injuries (54.1 %) and for those 75 years or older in serious injuries (47.5 %) and fatalities (64.3 %). For pedestrian crossing directions on the crosswalk, the pedestrian crossing from the forward left-side corner to the right-side corner exhibited the highest percentage in the daytime (39.2 %), and the opposite direction of crossing from the right-side corner to the forward left-side corner exhibited the highest percentage in the nighttime (39.6 %). The characteristics obtained in this study will contribute to the development and evaluation of advanced safety systems that are specialized for right-turning maneuvers of light-duty trucks.
