The activity approach (AA) to transport modelling originated during the 1970's as a response to the widely perceived shortcomings of the prevailing four-stage, trip-based transport modelling framework. The activity approach challenged the fundamental assumptions of the framework by focusing on the role of travel as a means of enabling people to engage in spatially and temporally distinct activities. It was argued that observed patterns of trip making should be seen as a consequence of an individual's desire to participate in activities and that the analysis of travel behaviour should therefore be based on an understanding of the linked sequence of activities in which people engage during a day. This formulation was heavily influenced by the work of geographers such as T. Hagerstrand and F. Chapin, and by work carried out on the use of time budgets during the 1960's by A. Szalai. The main questions addressed by the approach in this report are the description and modelling of the daily and weekly activity and travel patterns as a function of the socio-economic situation of travellers and of the characteristics of the transport system.
