Summary	Space-time path analysis applies Torsten Hagerstrand's time geography to the study of tourist activity. In his 1970 address 'What about people in regional science?', Hagerstrand argued that an individual's life can be traced as a continuous path through a coupled space-time, hemmed in by capability, coupling, and authority constraints, and visualized in a 'space-time aquarium.' Applied to tourism, each visitor's day becomes a space-time path whose shape is governed by how fast they can move, where and when they must be co-present with others, and the opening hours and access rules of attractions. Shoval and Isaacson brought this framework into modern tourism research with GPS-derived paths, and movement-pattern work such as McKercher and Lau's connects the recovered activity sequences to a typology of how tourists use a destination.	Tourism carrying capacity assessment estimates the maximum level of visitor use a destination or site can sustain before its environment, infrastructure, host community, or visitor experience begins to deteriorate unacceptably. The concept, given its influential tourism formulation by A. M. O'Reilly in 1986, recognises that carrying capacity is not a single number but a set of limits operating across distinct dimensions — physical and ecological capacity on the resource side, social capacity on the host and visitor side, and economic capacity on the activity side — with the binding constraint being whichever is reached first. Carrying capacity is the conceptual engine behind Butler's Tourism Area Life Cycle, explaining why unmanaged growth leads to stagnation, and it underpins much of sustainable destination management even as it has been refined into more flexible, indicator-based frameworks.
