北京市城乡结合部公路高风险区域成因分析

Cause Analysis of High Risk District in the Urban-rural Conjunction Areas in Beijing

基于交通部西部项目'公路交通安全数据库'GIS平台的相关数据,以北京市通州区为例,采用'空间数据分析'的方法,以千万车公里事故率为依据对通州区公路交通安全服务水平进行划分,并以此分析公路高风险区域形成原因,给出治理办法.

The urban-rural conjunction areas is a particular product of the process of urbanization. Due to the dual urban-rural property, the transportation development characteristics in the urban-rural conjunction areas also have dissimilarities, and then cause some high risk districts on the highways. This article take Tongzhou district in Peking city as an example. According to the related data of the western project --＂Road traffic database＂ of the Ministry of Transportation and Communications, the authors use spatial data analysis method, and divide the level of safety service（LOSS） with the accident rate per ten million cars per kilometer to research whether the highway traffic accidents present a specific distribution on the two-dimensional or not. Finally, the authors get the distribution map and then analyze the formation reason of the high risk district. An approach to tackle the problem is proposed.
