The 'human activity approach'to the study of travel behaviour represents a synthesis of
concepts and analytic approaches partially drawn from several subdisciplines concerned …

Trip chaining is a phenomenon that we know exists but rarely investigate. This could be
attributed to either the difficulty in defining trip chains, extracting such information from travel …

The household activity pattern problem of analyzing/predicting the optimal path of
household members through time and space as they complete a prescribed agenda of out …

This paper is concerned with choice set formation in the intraurban context where choice
alternatives explicitly involve the spatial dimension. Its purpose is to develop an operational …

This work extends the conceptual argument for the use of ellipses to portray activity spaces
and offers one example of how the ellipse construct can be used to analyze urban travel …

The use of geographic information systems in determining transit service areas has not
progressed far beyond simple buffering operations even though there is widespread …

In this paper, we develop an approach for modeling the daily number of non-work, out-of-
home activity episodes for household heads that incorporates in its framework both …

Joint household travel, with or without joint participation in an activity, constitutes a
fundamental aspect in modelling activity-based travel behaviour. This paper examines joint …

Transportation planners are increasingly looking to reduce drive-alone travel. However, the
existence of complex tours could be a major barrier to the shift from drive-alone to public …

This paper develops a spatio-temporal data model to support activitybased transport
demand modelling in a GIS environment. This so-called mobilityoriented spatio-temporal …
