"The Access to Jobs and Workers Via Transit tool is a free geospatial data resource and web mapping tool for comparing the accessibility of neighborhoods via public transit service. Its indicators summarize accessibility to jobs as well as accessibility by workers, households, and population.
<br />
Coverage is limited to metropolitan regions served by transit agencies that share their service data in a standard format called GTFS .
<br />
A collection of performance indicators and regional benchmarks for consistently comparing neighborhoods (census block groups) across the US in regards to their accessibility to jobs or workers via public transit service. 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 45 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."
