EPA modeled accessibility via transit by calculating total travel time between block group centroids inclusive of walking to/from transit stops, wait times, and transfers. Block groups that can be accessed in 30 minutes or less from the origin block group are considered accessible. Values reflect public transit service in December 2012 and employment counts in 2010. Coverage is limited to census block groups within metropolitan regions served by transit agencies who share their service data in a standardized format called GTFS.

All variable names refer to variables in EPA's Smart Location Database. For instance EmpTot10_sum summarizes total employment (EmpTot10)  in block groups that are reachable within a 30-minute transit and walking commute. See Smart Location Database User Guide for full variable descriptions.</abstract><purpose>This data can be used to evaluate the relative performance of neighborhoods in regards to their accessibility to jobs via public transit service. Among other applications, transportation planners can used this data as inputs when evaluating the potential traffic generated by proposed mixed-use developments using EPA’s MXD tool.</purpose><supplinf>http://epa.gov/smartgrowth/smartlocationdatabase.htm#trans30</supplinf></descript><timeperd><current>Ground condition</current><timeinfo><sngdate><caldate>2010</caldate></sngdate></timeinfo></timeperd><status><progress>Complete</progress><update>Irregular</update></status><accconst>None.</accconst><useconst>None.
