Even with your very basic model, I'd call NYC public transport a huge success, as Andrew wrote. A more realistic model would make it look even better. I doubt that it would even be possible to put that many additional cars on the road. As to the cost, I'd bet that compared to the cost of the extra congestion, pollution, etc., it's also a winner. I also question your statement that everything after Chicago is no good. For example Boston has about 390,000 passenger trips per year. The combined population of Boston, Cambridge, and Somerville (the three largest users) is about 735,000. Based on the NYC figures, that looks like a pretty good ratio. Boston may, of course, have a higher ratio of suburban commuters than NYC, and a more thorough look would have to take account of that. One thing that I agree with you on is the stupidity of statements like "public transportation fixes everything", or other unsupported generalities. Public transportation is certainly feasible in large cities, but there are obviously limits to where it makes sense. FWIW, about 20% of the US lives in the 100 most populous cities. -Chris ------------------------------------------------------------------------ | Christopher Judd, Ph. D.
