Abstract

In France, for example, aggregate models are still in much more common use than disaggregate models, even for modal split. The estimation of aggregate models is still therefore an important issue. In France, for most studies it is possible to use behavioural data from household surveys, which are conducted every ten years in most French conurbations. A method for the estimation of aggregate models is described in detail and was tested for the Lyon conurbation with data from the most recent household travel survey conducted in 1995/96. A variety of tests was conducted in order to identify the best application of the method and to test the stability of the results. It was found that this method always produces better results than the more traditional method that involves zoning aggregation. The paper presents both the methodology and the results obtained from different aggregation methods. In particular, an analysis is presented of how the choice of zoning system affects the results of the estimation. For the covering abstract see ITRD E126595.
