[see a separate paper by the
author, ‘Using Our Feet to Reduce Our Footprint: The Importance
of Scale in Life’ (1997) for the ‘NRFUT’ system of comparing the
‘footprint’ of different trips.]
The model rejects
the concept of the balanced transportation system, where users are assumed to be free to choose between many options. This is because choices incorporating factors that are ranked low generally have a high impact on other choices.
