在车联网应用发展的背景下，许多城市的私家车和出租车上安装了配备GPS设备的智能终端，产生着大量的时空轨迹数据.为挖掘这些数据蕴含的驾驶员出行特征，本文以北京市出租车时空轨迹数据为例，基于时空GIS的视角提出并实现了驾驶员居住地挖掘方法和作息规律性分析方法.样本实验结果一方面展示了驾驶员居住地空间分布，另一方面表明作息规律性总相似度在0.6–1之间的驾驶员数量较多，占到了总数的73.75%.通过本文方法挖掘的信息可为出租车的管理提供辅助决策，方法同样适用私家车时空轨迹数据的挖掘，对私家车出行规律的研究和掌握更有意义.
在車聯網應用髮展的揹景下，許多城市的私傢車和齣租車上安裝瞭配備GPS設備的智能終耑，產生著大量的時空軌跡數據.為挖掘這些數據蘊含的駕駛員齣行特徵，本文以北京市齣租車時空軌跡數據為例，基于時空GIS的視角提齣併實現瞭駕駛員居住地挖掘方法和作息規律性分析方法.樣本實驗結果一方麵展示瞭駕駛員居住地空間分佈，另一方麵錶明作息規律性總相似度在0.6–1之間的駕駛員數量較多，佔到瞭總數的73.75%.通過本文方法挖掘的信息可為齣租車的管理提供輔助決策，方法同樣適用私傢車時空軌跡數據的挖掘，對私傢車齣行規律的研究和掌握更有意義.

With the development and application of mobile positioning technology, more and more private cars and taxis are equipped with GPS, and produce a great deal spatio-temporal trajectory data. In order to mine the characteristics of drivers based on these data. This paper studies spatio-temporal trajectory data of taxi in Beijing city from the perspective of time geography,the driver residence mining method and rule analyzing method of work and rest is put forward and is realized, and the experimental results are analyzed. Sample experimental results show the space distribution of the driver residence, and show that the number of driver routines of the total similarity between 0.6–1, accounted for 73.75% of the total. The information mined through the method can provide decision support for the management of the taxi, and the method application for private car has important significance.
