Samenvatting
In the framework of the study into the structuring effect of the infrastructure, the development of a land use-transport-interaction model (GTI) is started. TIGRIS is a prototype of this GTI model and has three functions: (1) to show that an interactive GTI model can be really built; (2) to visualize the (im)possibilities of graphic interfaces; and (3) to make the framework on which the GTI model can be developed further. A description is given of the background and design of TIGRIS, and some results are summarized. By the results is studied per function in how far TIGRIS is successful and if there are possibilities for improvement.
