摘要
与城市地区相比,城乡结合地区交通具有事故频发、严重程度高等特点,虽经多方努力但效果有限,已成为影响我国交通安全的重点瓶颈地区。采集某城市城乡结合地区近3年来的事故数据,引入车辆保护性和攻击性指标作为车型安全性指标,基于多分类有序Logit模型设计了城乡结合地区不同车型安全性分析方法,确定了各车型安全性,深入分析了各因素对车型安全性影响,并提出相关改善建议。
Compared with urban areas,urban-rural binding regions have the characteristics of frequent accidents and high severity. Although the effort has been made in many ways,the effect is limited. The urban-rural binding region has become a key bottleneck area that affects China’s traffic safety. The accident data of the urban-rural binding regions of a city in the past three years were collected,and the vehicle CWI( crash worthiness index) and CAI( crash aggressivity index) were introduced as the vehicle type safety indexes. Based on the polytomous ordered Logit model,the safety analysis method of different vehicle types in the urban-rural binding area was designed,and the safety of each vehicle type was determined.The influence of various factors on vehicle safety was analyzed in depth,and the relevant improvement suggestions were put forward.
