【摘要】：研究行人与车辆碰撞事故中下肢损伤风险,并确定碰撞速度和行人年龄、身高以及体重等损伤相关参数值在下肢轻微损伤组和严重损伤组之间的分布是否存在显著差异。为此,首先从德国深入事故研究数据库(GIDAS)中挑选出354个带有行人下肢损伤的案例来进行单因素方差分析,接着利用逻辑回归分析方法建立行人下肢严重损伤风险函数模型,分析车辆碰撞速度和行人年龄、身高以及体重对行人下肢严重损伤风险的影响。分析结果表明:碰撞速度和行人年龄是影响行人下肢严重损伤的显著性因素,而体重与身高不是影响行人下肢严重损伤的显著性因素;并且行人下肢严重损伤风险与碰撞速度以及行人年龄正相关。当碰撞速度为43 km/h时,行人下肢严重损伤风险达到50%。
[Abstract]:To study the risk of lower extremity injury in pedestrian and vehicle collision accident, and to determine whether there are significant differences in the distribution of injury related parameters such as collision speed, pedestrian age, height and weight between mild and severe lower extremity injury groups. For this reason, 354 cases with lower extremity injuries were selected from GIDAS-based accident research database in Germany to carry out one-way ANOVA, and then the risk function model of serious injuries of lower extremities was established by using logical regression analysis. The effects of vehicle collision speed, pedestrian age, height and weight on the risk of serious lower limb injury were analyzed. The results showed that collision speed and pedestrian age were the significant factors affecting the serious injury of lower extremity, but weight and height were not the significant factors affecting serious injury of lower extremity. And the risk of serious lower limb injury is positively correlated with collision velocity and pedestrian age. When the collision velocity is 43 km/h, the risk of serious lower limb injury reaches 50%.
