Your units are off. You're calculating dollars per mile per year. The article talks about dollars per mile, which could be an imprecise way of talking about dollars per mile per year, but taking the words at face value gives about 1 cent per mile at 20 mpg, the Department of Transportation's average fuel economy as of 2005. If you include the federal 18.4 cent tax, you get 1.92 cents per mile.
- patrickgzill 17y agoI think both our units are off. If the units represent 20-30 cents per car per mile traveled, then my question is, what manner of gold and silver is used in constructing Texas roads?
- natrius 17y agoLet's work with an actual example, the expansion of Interstate 10 in Katy, TX. http://www.chron.com/disp/story.mpl/metropolitan/5450155.html http://www.chron.com/disp/story.mpl/metropolitan/5450155.htm... Estimated cost: $2.8 billion Traffic: 207,000 per day (http://www.katyfreeway.org/background.html http://www.katyfreeway.org/background.html) Length: 22 miles Cost per mile per daily trip: $614.84 If we're paying it off over 20 years, that's 8.4 cents per mile driven. This doesn't include any necessary maintenance over those 20 years. I doubt the 20-30 cents figure is wrong. The person who was quoted was an elected official who dealt with a lot of transportation issues.
