摘　　要：为提升城市交通安全管理水平,对我国12个典型大城市的交通事故变化趋势以及安全影响因素进行了纵向分析和横向对比。建立了多元线性回归模型,探讨路网特征、出行方式结构等重要影响因素的作用效应。结果表明:不同城市的交通安全发展呈现出规律性特征,科学紧凑的交通路网布局有利于提升交通系统的安全性能;增大集约型公交出行比例和慢行交通出行比例将有效降低城市交通事故死亡率。To improve the urban traffic safety management,this study conducted city-level traffic safety comparison and analysis in 12 Chinese cities.Multivariate linear regression model was used to explore the potential impacts of several key factors on traffic safety,such as the road network characteristics and different travel mode shares.Modeling results showed that the development of traffic safety in different cities have regularity characteristics.Narrow roads and dense networks have potential strength in enhancing the traffic safety performance.Higher proportion of public transport and non-motorized traffic were associated with less traffic fatality rate.
