ABSTRACT |
The factors in fatal injuries to cyclists in collisions with five different types of vehicles were examined using
data from the Institute for Traffic Accident Research and Data Analysis in Japan for the period 2004 ~ 2013. The vehicle types
were sedans, minivans, box vans, light passenger cars (LPCs), and light cargo vans (LCVs). The analyses focused on cyclist
age, gender, main body regions that suffered fatal injuries, and vehicle travel speeds. Cyclists aged 75+ years made up the
largest group of fatalities in collisions with sedans, box vans, LPCs, and LCVs, whereas those aged 13 ~ 64 years made up
the largest group of fatalities in collisions with minivans. Head injuries were the most frequent injuries in cyclist fatalities. The
percentage of head injuries in fatalities of cyclists aged 75+ years was significantly higher than that for cyclists aged 13 ~ 64
years for box vans, but significantly lower for sedans, LPCs, and LCVs. For sedans, the percentage of hip injuries in fatalities
of cyclists aged 75+ years was significantly higher than that of cyclists aged 13 ~ 64 years. Cyclist fatalities due to hip injuries
were significantly more common for females than for males in collisions with sedans, LPCs, and LCVs. |
