In 1960's, many recreation trip demand models were developed for regional planning and transportation planning under the hard constraint of data sources. In this paper the estimated future demand and the models are evaluated and the improvement of the generation, distribution and modal split models for recreation trips is discussed. The advantage of the disaggregate models for each step that were developed in later 1970's is shown comparing the conventional models.
