time geography

(from Wikipedia):

Time geography or time-space geography traces its roots back to the Swedish geographer Torsten Hägerstrand who stressed the temporal factor in spatial human activities. The time-space path, devised by Hägerstrand, shows the movement of an individual in the spatial-temporal environment with the constraints placed on the individual by these two factors. Three categories of constraints were identified by Hägerstrand:

  1. Authority - limits of accessibility to certain places or domains placed on individuals by owners or authorities
  2. Capability - limitations on the movement of individuals, based on their nature. For example, movement is restricted by biological factors, such as the need for food, drink, and sleep
  3. Coupling - restraint of an individual, anchoring him or her to a location while interacting with other individuals in order to complete a task
