Abstract

hot issue in the area of spatio–temporal databases [7]. While existing Moving Object Simulators (MOSs) address different physical aspects of mobility, they neglect the important social and geo–demographical aspects of it. This paper presents ST–ACTS, a Spatio–Temporal ACTivity Simulator that, using various geo–statistical data sources and intuitive principles, models the so far neglected aspects. ST–ACTS considers that (1) objects (representing mobile users) move from one spatio–temporal location to another with the objective of performing a certain activity at the latter location; (2) not all users are equally likely to perform a given activity; (3) certain activities are erformed at certain locations and times; and (4) activities exhibit regularities that can be specific to a single user or to groups of users. Experimental results show that ST-ACTS is able to effectively generate realistic spatio–temporal distributions of activities, which make it essential for the development of adequate spatiotemporal data management and data mining techniques.
