Frontal Collision Study and Passenger Safety in Japan
This study analyzes frontal collision accidents involving Category N1 vehicles in Japan, focusing on accident rates, injuries, and fatalities by age and gender. Female passengers aged 65 and over exhibit a higher incidence of injuries and fatalities, emphasizing the need for targeted safety measures for vulnerable demographics in vehicle collisions.

Fatal and Serious Injury Rates for Passenger Seat Occupants in Category N1 in Japan by Age and Sex Fatal and serious injury rates for occupants in the front seat of N1 category vehicles 25% 21.9% Fatal and serious injury rates 20% 17.2% 15% 10% 7.0% 7.3% 4.0% 5% 3.2% 0% Aged 24 and under Aged 25-64 Aged 65 and over Male Female Fatal and serious injury rates are higher among the elderly than among the young. The rate is higher for women than for men among the elderly.
Summary A 10-year accident study was conducted from 2012 to 2021 for passenger seat occupants of N1category vehicles weighing 2.8 tons or less. Of the data on accidents resulting in minor injuries to front seat passengers in N1 category vehicles, female passengers aged 65 and over accounted for the second highest percentage of injuries (22%). The high incidence of minor injury accidents suggests that the percentage of elderly female passengers in the front passenger seat of N1 vehicles is high in Japan. Among the data on accidents resulting in the fatal or serious injury of front seat passengers in N1 category vehicles, female passengers aged 65 and over accounted for the highest percentage of injuries (50%), accounting for about half of the total. The fatality and serious injury rate for front seat passengers of N1 category vehicles was higher for females than for males amongst the elderly. It is possible that elderly female front seat passengers are more likely to be involved in fatal and serious injury accidents than elderly male front seat passengers. => Based on the above data, when protecting front seat passengers of N1 category vehicles, elderly female passengers need to be protected in Japan, and therefore, the chest injury value of the front seat dummy specified under UN R137 should be revised to take elderly passengers into account.
