The invention provides an accident data and characteristic factor-based accident multiple-occurrence point recommendation method, which solves the problem of poor adaptability of the existing traffic management system to different traffic scenes, and comprises the following steps of: obtaining accident parameters; carrying out dimensionality reduction on the accident corresponding matrix; performing clustering analysis on the matrix after dimension reduction; calculating an outlier factor LOF and eliminating outliers; and grading and ranking the multiple points. The method has the advantages of being good in accident analysis effect, good in adaptability to different traffic systems and the like.
本发明提供了一种基于事故数据和特征因素的事故多发点推荐方法,它解决了现有交通管理系统对于不同交通场景适应性较差问题,其包括如下步骤:获取事故参数;对事故对应矩阵降维;对降维后的矩阵做聚类分析;计算离群因子LOF并剔除离群点;对多发点打分排名。本发明具有事故分析效果好、对于不同交通系统适应性好等优点。
