In this study, we identify the most common crash configurations, injured body regions, and injuries in low-severity crashes (here defined as crashes with EES below 35 km/h). In addition, we investigate how sex, age, anthropometry (weight, height, and BMI), car size, and registration year influence the risk of sustaining an AIS2+ injury.
Injured belted occupants are predominantly of relatively average size and age, closely following the distribution of all belted occupants exposed to crashes. Likewise, the crash configuration distribution of low severity crashes resulting in AIS2+ injury closely matched the distribution of all low-severity crashes, where a fullfrontal crash was the most frequent crash configuration. Females in general, are at a higher injury risk compared to males. Thereto, injured occupants were on average 5 years older compared to all occupants exposed to lowseverity crashes. Head, thorax, and upper extremities are the most commonly injured body regions for middleaged occupants while younger occupants are more frequently injured to head, and elderly more frequently injured to thorax. The majority of the injuries was of AIS2 level.
Occupants in low-severity crashes were in general at a relative low injury risk (5.6%). To further reduce the relative low injury risk presents a substantial challenge since current injury risk functions, evaluation tools, and assessment methods are developed for substantially higher injury risks and crash severities and might therefore not be applicable for these high-exposure low-severity crashes.
