Abstract

Abstract:

The distribution of multiple injuries across body regions of vulnerable road users (VRUs) in vehicle collision accidents was investigated to provide data support for assessing accident occurrence probabilities. 159 cases of in-depth traffic accident were selected from the existed VRU traffic accident database with video (VRU-TRAVi). The impact velocities were acquired by using the method of Direct Linear Transformation (DLT) and the frame-by-frame video analysis. The body injury regions were evaluated by using the Abbreviated Injury Scale (AIS) and the Maximum Abbreviated Injury Scale (MAIS). The results show that the head and the lower limbs are the most common sites of injury. The head injuries total 139 cases, accounting for 87.4% of the total. Lower limb injuries reach 111 cases (69.8%), with the severity being classified into three grades: the minor (AIS 1), the moderate (AIS 2), and the serious (AIS 3). Dual-site/triple-site injuries reach AIS 2 or above, the combination of the head-thorax and abdomen/the head-thorax and abdomen-lower limbs is the most frequent, accounting for 49.0% and 58.8%. The highest proportion of cases is the Maximum Absolute Injury Severity (MAIS) score of 6 in the head region, accounting for 95.7% of all MAIS 6 cases, it is also the primary cause of fatalities in VRUs.

Key words: vehicle collisions, vulnerable road users (VRUs), in-depth accidents, multiple injuries region
