The True Cost of Commuting from the Exurbs
The study was prepared by the Center for Neighborhood Technology in Chicago for the Urban Land Institute.
"In San Francisco, for instance, a household with the median city income of $66,523 has estimated monthly transportation costs of $792. In nearby cities the monthly estimate remains in triple digits, such as Berkeley ($858) or Sausalito ($885).
For families in more distant automobile-reliant suburbs, though, the monthly transportation costs spike. The estimate for Antioch is $1,311, for instance, while in Livermore it's $1,281. Cities with little connection to transit also suffer - such as Pacifica, where a household's monthly transportation is estimated to cost $1,246."
