概要	Time geography is a framework, introduced by Torsten Hägerstrand in 1970, that represents human activity as continuous trajectories through a joint space-time coordinate system rather than as static points on a map. Each individual traces a space-time path through the 'space-time aquarium', and the set of all locations that can be reached and returned from within a time budget forms a space-time prism, whose spatial footprint is the potential path area. The framework grounds accessibility and mobility in the inescapable fact that people can be in only one place at a time and that movement consumes both space and time.	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.
