Mr. Shoup expanded upon this article and in 2005 released a full-length book under the same title, available from at least one of the more popular online booksellers. It's a great read for planners, civic advocates, or people who want to learn more about the devastating negative impact subsidized parking is having on our communities.

It has been a long time since I've read his work, but one of my take-aways was that most communities set minimum parking requirements (i.e. you must provide 50 parking spaces for every 1,000 sq/ft retail space) for new developments which lead to large asphalt oceans of parking that sits unused for most of the year. it leads to increased rainwater run-off, inefficient use of land and indirectly and negatively impacts pedestrian and bicycling connections by increasing the distance between retailers / office buildings / multi-use residences unnecessarily.

most planners are now of the belief that minimum parking requirements should be set by the free market (a developer will make sure his customers will be able to park, but is very sensitive to wasteful spending and won't create so much that most go un-used throughout the year) and the local planning departments should instead set maximum parking limits (for example no more than 10 per 1,000 sq/ft of space).
