Accessibility was modeled 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. Indicators reflect public transit service in December 2012 and employment/worker 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.This data can be used to evaluate the relative performance of neighborhoods in regards to their accessibility to jobs or workers via public transit service. For instance, an employer or business may use this data to identify neighborhoods that have high transit accessibility to the regional population or workforce. In other words, it may use the data to identify locations that are easy to reach via transit for the greatest possible number of residents or potential workers. Such information can be valuable to facility siting decisions. Similarly this data can be used to identify residential locations that have high accessibility to jobs by transit. Regional benchmarks provide comparisons to better understand the performance of a block group compared to the best or average performance among all block groups in the surrounding metropolitan region.http://epa.gov/smartgrowth/smartlocationdatabase.htm#trans30Ground condition2010irregularNone.None.
