Abstract

Time geography uses space-time volumes to represent the possible locations of a mobile agent over time in a x-y-t space. Space-time volumes are qualitative statements, enabling qualitative analysis. In this paper these statements will be quantified, modeling an agent's possible locations from a stochastic perspective. With such a model time geography can be improved in expressiveness as well as accuracy.
