摘要： 通学路交通环境质量关乎青少年群体上下学的基本出行，对其开展安全性评估具有重要意 义。以北京市为例，基于开源数据挖掘集成五环快速路范围内391 所中小学的通学路交通环境数 据，利用新媒体公众参与平台“路见”获取1 722 份公众提案数据。进一步从客观和主观视角构建 物理性安全指数和感知性安全指数相结合的通学路交通环境安全性评估体系。实证分析发现：位于 城市核心的西城区和东城区通学路交通环境的安全性最高，海淀区和朝阳区次之，外围丰台区最 低；超过1/4 的学校存在多处安全隐患，占道停车和过街设施不足是引发通学路安全风险的重要 原因。

Abstract： Since the quality of school route traffic environment affects the school-bound teenager trips, it is important to assess the safety of school routes. Taking Beijing as an example, the paper acquired the data of 1,722 suggested improvements from the public opinion by means of “Pinstreet”, a new media platform featuring public participation activities based on the school route traffic environment data of 391 primary and middle schools within the express fifth ring road. These data are explored and integrated with open source data. The paper develops a traffic environment safety assessment system for school route in combined physical safety indicators and perceived safety indicators from the objective and subjective perspectives. The results show that: the traffic environment safety is the highest in Xicheng District and Dongcheng District located in the core area of Beijing, followed by Haidian District and Chaoyang District; the traffic environment safety of the Fengtai District is the lowest. More than 1/4 schools have multiple safety inefficiencies: parking right on roadway and lack of pedestrian crossing facilities are key risky problems on school routes.
