After completing my recent analysis of WMATA’s Metrorail fare increase, I decided to do some more research to better put the fares in a national context, finding D.C. Metro riders pay some of the highest subway fares in the nation. I then did a side-by-side comparison with San Francisco’s BART, considered a sister system to the D.C. Metro. The analysis of BART fares from a downtown San Francisco station shows that Bay-area suburban commuters enjoy even cheaper per-mile fares than their D.C. counterparts.
