摘要: 介绍了事故多发点的分析方法, 建立了事故多发点判别模型, 并给出了其算法, 根据中国交通流的特点, 开发了事故多发点数据库, 使事故多发点的鉴别工作能够快速进行。Abstract: The methods for analyzing accident-prone locations were described. The model for its examining was developed. The database for its identifying was developed according to Chinese traffic flow characteristics. With the database, the identification can be carried out rapidly.
