A MODE-SPLIT MODEL WITH MULTIPLE TRANSIT MODES

The RATP (Regie Autonome des Transports Parisiens) has recently started the development of a disaggregate travel demand modelling system for the Ile-de-France (Paris) region. The first step in the developing of this model system was to estimate and validate a modal-split model for trips to work. This paper gives details on the data sources used for model estimation and presents a basic 6-mode model with 3 transit modes estimated with these data. This model was validated by applying it in a disaggregate fashion to predict the effects on modal-split of a metro extension opened in 1977. The model predictions were compared with the results of a home interview "before and after" survey, and the model was found to predict satisfactorily. The need for multiple transit mode representation is discussed, and it is demonstrated that, for most trips, several alternative transit paths are available. One section describes models using different model representations of transit. It is concluded that, for the Paris region, the more accurate representation of transit in the multiple transit mode approach justified the extra complexity. (TRRL)
