OK, I saw some of the math on this thread and I couldn't resist adding to it. I've always been curious how much money the Metro system keeps in the St. Louis area by reducing the amount of gas we as a community use (assuming almost all of that gas money would have gone to refineries/drilling operations far far away). Does anybody know how many passenger-miles Metro logs daily? I couldn't find that info, but according to Wikipedia the system carried about 150,000 passengers daily in FY 2007. If you assume that the average trip is 5 miles and that without Metro each person would drive their own car that gets 20 miles per gallon at $2.50 per gallon, you get:
150,000 x 5 miles x (1 gallon / 20 miles) x ($2.50 dollars / gallon) ~ $95,000
So that's about $95k that stays in St. Louis every day because people didn't have to drive cars. That works out to about $34 million annually. Obviously there were a lot of estimations/assumptions in that calculation and it neglects any money that Metro has to spend on gas (which I'm sure isn't negligible), but I thought that number was interesting. I'm curious if things like this are included in the studies on Metro's economic impact.
