תקציר	GPS trajectory analysis is the pipeline that turns raw streams of timestamped location fixes into structured, meaningful mobility information — the stops where a person dwells, the trips between them, the transport modes used, and the network routes actually travelled. Following the trajectory-data-mining framework synthesized by Yu Zheng in 2015, it cleans noisy positions, segments movement into stays and journeys, snaps points onto road or transit networks, and infers behaviour and recurrent patterns. It is the foundation for activity-space, travel-demand, and mobility studies built on smartphone and vehicle tracking data.	Activity space analysis measures the geographic area within which an individual moves and carries out their routine daily activities — home, work, shopping, leisure — and the travel that links them. By delineating this lived spatial footprint from observed visit locations, it reveals how far and in what directions people actually range, and what environments they are exposed to in the course of ordinary life. It bridges the behavioural geography of Golledge and Stimson with modern mobility and health research that links where people go to the contexts they encounter.
