The American Public Transit Association (APTA) just released their Transit Savings Report, which estimates how much people save monthly and annually from taking transit instead of driving. Portland is ranked #11 among US cities, with monthly savings of $856 and annual savings of $10,269. The report uses the cost of a monthly transit pass to represent transit costs, while driving costs are calculated by plugging the local average fuel price and parking cost into AAA’s formula for the cost of driving. The report does not take into account time costs, of course, and relies on certain assumptions about per capita vehicle miles traveled, but overall gives a good representation of how much someone could potentially save by switching to transit. It is also interesting to compare cities–for example, Seattle ranks better than Portland at #4, probably due to the much higher cost of parking in Seattle.
