Transportation and planning : some myths reviewed.

Variety of beliefs, ideas and convictions which appear to surround the field of transportation and planning are discussed. The economic myth may take a number of forms. The reverse side of this is the relative capacity myth. A related group of myths still in the economic sphere, centre on the concept of cost/benefit or cost effectiveness, or to put it more simply, relative efficiency. A few more myths are, more or less, in the field of economics. Finally there are what might be called the procedural fictions-the myth of predictability and the myth of extrapolation. What is really involved, perhaps, is the myth of reality.
