This posting was originally from pednet, a pedestrian and bicycle discussion group. This is now in the Official Plan of our regional government. I developed the concept in a short 1992 paper that I will append below. But it will not increase longer trips if the costs are passed on to the traveler, rather than being subsidized by all. The following factors represent choices in urban transportation.
Some choices are more environmentally friendly than other choices.
Each trip can be ranked on the nine factors below. The author recognizes that, although readers will find the hierarchy to be logical, the effect of applying it will seem radical. What must be noticed is that 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 of the extreme range in the choices possible. Where those two trips intersect, our present system makes the woman wait for the man, and in winter, will cause the snow to be piled to make a direct trip impossible for her.
