An Integrated Spatio-Temporal GIS Toolkit for Exploring Intra-Household Interactions

To facilitate the investigation of intra-household interactions, an integrated spatio-temporal geographic information system (GIS) toolkit was developed. This paper describes this toolkit, which is comprised of two tools: the Space-Time Coincidence Analyst and the Space-Time Path Visualizer. The Space-Time Coincidence Analyst identifies joint activity/travel episodes undertaken by household members. The core of this tool is a set of flexible criteria for classifying episodes as either joint or independent. The Space-Time Path Visualizer not only displays space-time paths for household members, but also shows joint episodes undertaken by any two household members together. The toolkit can be applied to any household-based, activity/travel data set so long as required information is specified by the user. Results from an application of the toolkit to the Toronto Activity Panel Survey 2002–03 data set suggests that considerable variation exists in the number of joint activity/travel episodes identified using different classification criteria. Specifically, when using restrictive criteria (i.e., same timing, specific activity type/travel mode), only 2,265 joint activity/travel episodes are identified compared to 8,791 when using more flexible criteria. The results also show that certain key attributes for independent and joint activity/travel episodes (i.e., frequency per household, starting time, ending time and duration) also vary under the different classification criteria. The composition of joint episodes are compared when using different criteria, with findings that have direct implications for improving the design of future activity/travel surveys.
