Abstract: Using the SITRAMP dataset, which was collected in the Jakarta metropolitan area, Indonesia, over four consecutive days, this study examines day-to-day variability of individuals' activity spaces. The impact of individual heterogeneity and variability of transport network conditions on day-to-day variability of activity spaces is also investigated. Results show that individuals' activity spaces vary from day to day and between different individuals. The activity space of other household members was found to be the most significant factor influencing an individual's activity space. Against the common belief in developing countries that better traffic conditions make individuals travel farther, results show that higher road-network travel speed and better road surface conditions within the home zones actually encourage individuals to visit a more compact set of activity locations and/or visit fewer activity locations. Smoother road surface conditions and higher travel speeds within home zones also bring the centroid of activity locations closer to individuals' home locations. Furthermore, day-to-day variability analysis of individual activity spaces showed that weekday activity spaces are more compact than those at weekends. Moreover, it was found that students' activity spaces show most variability, while those of nonworkers have the lowest variability.
