N2 - This paper develops a spatio-temporal data model to support activity-based transport demand modelling in a GIS environment. This so-called mobility-oriented spatio-temporal data model conceptualizes the spatial and temporal interaction of travel and activity behaviour using the concept of mobility. In other words, activity patterns are conceptualized as a sequence of staying at or travelling between activity locations. The model can support the analysis and queries of activities from different perspectives, i.e. queries can be location-based, time-based, and person-based. It can also support activity-based modelling by identifying spatial and temporal opportunities for activity participation. The conceptual and logical designs of the data model are presented. A prototype system based on the data model is implemented in Arc View. The prototype is illustrated and tested by a case study based in Hong Kong.
