| 摘 要： | 为了分析交叉口交通事故严重程度的影响因素，在对北京周边无信号三路交叉口交通事故数据调查的基础上，建立的累积Logistic模型，可为我国交叉口严重交通事故的预防提供科学依据。模型分析结果表明，交叉口转弯车辆比例、控制方式和土地开发强度对无信号三路交叉口交通事故的严重程度有显著影响。

| Abstract: | In order cumulative Logistic model to analyze the factors has been established on that affect the severity the basis of investigating of traffic accidents, the the data about the traffic accident at unsignalized three-phase intersection in the peripheral area around Beijing. It can provide scientific reference for preventing the serious traffic accident at the intersection. The analysis results of the model have indicated that the proportion of turning vehicles, control mode and the land-use intensity have remarkable influence on the severity of traffic accidents at unsignalized three-phase intersections. |
