N2  - A threshold gravity model and its possibilities as a planning and forecasting tool for transport problems are presented. The models are based on the earlier papers of the authors. The principal ideas concerning the development of the threshold value gravity model are presented. The new findings are the behaviour of models in representing the real mobility patterns of the population seeking central services. There is an attempt to predict some of the future travel intensities at different distances from the central places.<p />
