出租车GPS轨迹数据挖掘应用研究进展

Research on the progress in mining and applying taxi GPS trajectory data

在出租车的运营过程中,产生和积累了大量的GPS轨迹数据。出租车轨迹数据不仅反映出租车的行驶路线,同时也是城市交通状态与城市结构规划的一种数据映射,其中蕴含着丰富的信息,对城市的智能交通、智慧城市规划有着非常重要的意义。文章综述了近十年国内外出租车轨迹数据挖掘应用的相关研究,从个性化路径规划、城市规划和改善出租车服务三方面阐述其研究现状,并对出租车轨迹数据挖掘应用所面临的挑战以及未来的研究前景进行了探讨。

During the operation of the taxi,a large amount of GPS trajectory data is generated and accumulated.Taxi trajectory data not only reflects the driving route of the taxi,but also a data mapping of urban traffic status and urban structural planning.It contains a wealth of information and is of great significance for urban intelligent transportation and smart city planning.This paper summarizes the related research on the mining and application of taxi trajectory data at home and abroad in the past ten years,and elaborates its research status from the aspects of personalized path planning,urban planning,and improving taxi service.The challenges faced by taxi track data mining and application,and future research prospects are discussed as well.
