The D.C. metropolitan area has some of the best transit accessibility to jobs in the country, according to a new report from the University of Minnesota.

Using transit schedules from January of this year, the study examined 46 of the 50 largest metropolitan areas in the U.S.

In the study, rankings were determined by a weighted average of accessibility, giving a higher weight to closer jobs. Jobs reachable within 10 minutes were weighted most heavily; jobs were given decreasing weight as travel time increases up to 60 minutes. Travel times were calculated using full transit schedules for the 7 to 9 a.m. period. The calculations include all components of a transit journey, including “last mile” access and egress walking segments and transfers.

For the D.C. area, the study looked at schedules from Arlington Transit, the D.C. Circulator, Fairfax Connector, Maryland Transit Administration, Montgomery County’s Ride On and Virginia Railway Express. It found that 335,139 jobs in the D.C. area are accessible by public transit within 60 minutes, while 47,759 are reachable within 30 minutes and 1,362 within 10.

Of course, the report looked at schedules, not the actual performance of the systems commuters rely upon. This information should stress the importance of making the Metro system more reliable for daily commuters, lest we squander our existing accessibility.
