Project Details


The importance of the transportation area was evidenced by a report from several international organisations, which stated that the demand for transport services is expected to grow considerably as incomes rise, the trend toward urbanization continues and the process of globalisation moves forward. In order to meet this rising demand and because governments cannot afford to allow transport constraints to have a negative impact on the future competitiveness of their products, considerable future long-term investments are indispensable. In order to better guide and substantiate decisions of transportation planners, the use of traffic and transportation models is advocated. From an international research perspective, activity-based transportation models have set the standard for modelling travel demand. Despite the clear advantages of this type of models, they haven’t however been put into practice in Flanders. This project, coördinated by Prof. Geert Wets, director of IMOB (LUC), intends to develop an activity-based transportationmodel for Flanders. It’s innovative in that it introduces computer-aided instruments for data collection on travel behaviour. Respondents’ travel behaviour will be recorded by a GPS-aid and questionned by computer. The model wil also be dynamic, so to more easily adapt to sudden changes in activities. The specific worktask of TOR consists in exploring how time budget data can be incorporated in the process of simulating travel behaviour. Besides IMOB and TOR, three other research groups participate to this project, namely the Urban Planning Group (TUEindhoven), VITO and Onderzoekscel Architectuur, Mobiliteit en Omgeving (PHL).
