摘　　要：从出租车轨迹数据中挖掘载客热点路段,能够为城市交通道路的规划和出租车的运营管理提供重要依据。以北京市出租车原始轨迹数据为基础,设计并建立了出租车载客行驶的载客数据模型,利用该模型对相似的载客轨迹信息进行了挖掘,结合时空信息提取并分析了不同时段的热点路段。通过北京市交通发展年度报告验证了该模型和挖掘方法的正确性和有效性。The mining of the hot sections for taxi to carry passengers from trajectory data of taxis can provide an important basis for urban traffic road planning and taxi operation and management.Based on the original trajectory data of taxis in Beijing,we design and build a passenger data model of taxi carrying passengers.We use the model to mine similar passenger carrying trajectory information,and extract and analyze the hot sections in different time periods by combining spatiotemporal information.Finally,we use the annual report of Beijing transportation development to verify the correctness and effectiveness of the proposed model and mining method.
