Abstract:The distribution of multiple injuriesacross body regions of vunerable road users (VRUs)in vehicle colision accidents was investigated to provide data support forassessing accident occurrence probabilities. 159 cases of in-depth trafc 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) andthe frame-by-frame videoanalysis.Thebodyinjury regions were evaluated byusing the Abbreviated Injury Scale(AlS)and the MaximumAbbreviated Injury Scale (MAlS).Theresults show thatthe headand the lower limbsare the most common sites of injury.The head injuries total139 cases,accounting for 87.4% of the total. Lower limb injuriesreach111 cases (69.8%) ，withthe severity beingclassified into three grades:the minor (AIS1),themoderate (AlS2),and theserious(AlS3).Dual-site/triple-siteinjuriesreachAlS2orabove,the combinationof the head-thoraxandabdomen/the head-thorax and abdomen-lowerlimbs is the most frequent, accounting for 49.0% and 58.8% .The highest proportionof cases is the Maximum Absolute Injury Severity (MAIS) score of6 in the head region,accounting for 95.7% of all MAlS6 cases,it isalso the primary cause of fatalities in VRUs.

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