This articles pays some attention to theoretical thinking about urban form and traffic. The author has come up with a model of a car free city which is based on what he calls "proximity units" (the scale is determined by walking distance) and the "new centrality" (which look like metropolitan nuclei of large scale functions) which in theory is best organized in a ring at two-thirds of the urban radius. He develops this model of a car free city in order to make cost comparisons with a city with cars. He concludes that satisfying the need for mobility in his car free model city costs much less than in a model city with cars. Evidently this is not the last word on the subject. In his presentation however, the author pays more attention to practical problems and the use of networking in order to solve them. (A)
