Bernhard Schindlholzer wrote that “even though I am confident that there will certainly be significant growth in some areas (i.e. vehicle tracking, in-car traffic information) I doubt that someday everyone will be using Google’s “Search nearby” feature to find the next ATM, restaurant or supermarket…the majority of people still roam in just a few locations and in general they do not move far from home. Vacations and business travel are exceptions – the percentage of time individuals spend in locations they don’t know is very small.”

I may review one simple concept and one theory here, which are “Home Range Concept” and “Traffic Pattern Theory”.

Home Range Concept.                                                                                                     It is a concept that can be traced back to a publication in 1943 by W. H. Burt, who constructed maps delineating the spatial extent or outside boundary of an animal’s movement during the course of its everyday activities.

Traffic Pattern Theory.                                                                                                  A people’s daily activity pattern is pretty regular, which comprises of several major events, such as school, work, home, shopping.What happens here is if you are looking at the traffic pattern of a person, saying a full-time employed, 45 years, car, 3-person-household, one child, the regular activity route is so LIMITED.
