The paper gives reviews of the development and application of travel demand models for a major transportation study in the western part of the Randstad conurbation of the Netherlands. The study was carried out by the Dienst Verkeerskunde of the Rijkswaterstaat (the Traffic and Transport Engineering Division of the Ministry of Transport and Public Works). Model development was the reposnsibility of Cambridge Systematics Europe BV. The first part of the paper describes the aims and the context of the study in terms of the current and anticipated traffic problems of this part of the Netherlands. An advanced disaggregate model system and a novel aggregate model system were developed during the study; a short description of the assumptions of these modelling techniques is given in the paper. In the second part of the paper the application of both model systems will be extensively described. The objectives of the application will be explained with respect to national transportation plans in the Netherlands, such as the Structuurschema Verkeer en Vervoer (Traffic and Transport Structure Plan). The validation of the aggregate model system is described in detail. The correction of the aggregate model system involved the estimation of a number of factors; these are discussed in the context of the theoretical basis of modelling in the study. The input for the first forecast for a future year (1990 in the Zuidvleugel Study) is presented as well as some first results. The traffic volumes which the modal system predict are judged to be highly satisfactory. Some results based on the disaggregate model system will also be presented. The application of this system uses the aggregation technique of sample enumeration, providing relatively quick and cheap estimates of the effects of traffic management policies. The results are presented in the form of overall numbers of trips (or tours), average trip length and overall mode choice. A few examples of predictions concerning the effects of traffic management policies are given in this paper; these have also been judged to be very reasonable. The traffic management policies that are examined concern parking regulation in a big city, improving transit access to locations of employment and changes in public transport fares. The sample enumeration system is currently being used to answer policy questions concerning traffic management; other examples of its use may thus be available for presentation in the paper.
