Time geography

From Geography

Time geography emphasises constraints rather than choices on individuals within a historical setting. “An individual can never free himself from … constraints” (Hagerstrand, 1970).

Starting points:'

1. Each individual describes a path in time and space

2. Types of paths: life path, weekly path, daily path

3. Stops or stations delineated in space and time are essential elements of paths

4. Paths can be visualized in space-time plots

There are three different forms of constraints:

1. Capability constraints: In daily life humans are committed to different things like eating and sleeping to function well.

2. Coupling constraints: People are dependent from others to fulfill an activity. They are also dependent from possibilities within spaces. This is the result of human interactions.

3. Authority constraints: People are dependent from limited opening hours to fulfill their activities. For example; people aren't able to shop at 3 pm.

Hägerstrand came up with a idea of a space and time path to illustrate how a person finds and navigates his way in spatial environments. "The physical area around a given individual is reduced to a two-dimensional plane, on which his or her location and destination are represented as zero-dimensional points." (Pred, 1981).

Conclusion: Time geography links space and time into a coherent framework and is suitable for detailed comparison of access levels of different population groups.
