An integrated space–time environment is demanded by activity-based travel studies to facilitate the investigation of spatial and temporal characteristics of activities. The current geographic information system (GIS), which has been successful in supporting trip-based travel analysis, does not include an explicit time representation and therefore is incapable of supporting activity-based travel analysis efficiently. This study proposes a temporal GIS design that incorporates the space–time path concept of Hägerstrand’s time geography to facilitate the analysis of activities in a space–time context. The space–time path concept provides an efficient approach to organizing activities and travels in their space–time contexts and to supporting the investigation of spatiotemporal relationships between individuals. This study adopts the three-dimensional orthogonal space–time system in the temporal GIS design and develops representation and analysis functions related to space–time paths and individual activities. The proposed design is successfully implemented in a prototype system. The system provides an integrated space–time environment to effectively visualize activities and travels in their space–time contexts and analyze their spatiotemporal characteristics. Such a system offers useful tools to facilitate activity-based travel studies.
