Abstract

Abstract: According to the statistical data of Urumqi in recent 5 years , there were two categories for accident severity , including serious accidents and non-serious accidents. The accident severity was selected as the dependent variable and thirteen factors were selected as the candidate independent variables. The significant correlation between dependent variable and independent variables was analyzed by the combined stepwise method to obtain the most correlated factor group. The analysis model of accident severity was established based on Logistic model. And the model parameters were evaluated to obtain the most correlated factors that exerted significant influence on urban road accident severity. Then the model reliability was analyzed. It provides the basis for reducing the severity of traffic accidents

Key words: traffic safety, Logistic model, traffic accident severity

摘要： 根据乌鲁木齐市5 年的交通事故统计资料，将交通事故严重程度分为严重事故和非严重事故两类。以交通事故严重程度为因变量，从影响因素中初步选取13 个候选自变量，分析候选自变量与因变量之间的相关性，获得最具相关性的因素组合。采用二项Logistic 模型建立交通事故严重程度分析模型，对模型参数进行了估计，并对模型的可靠性进行了分析。相关研究可以为降低交通事故严重程度提供依据。
