Access to Jobs and Workers Via Transit Tool
Access to Jobs and Workers Via Transit is a free geospatial data resource and web mapping tool for comparing the accessibility of neighborhoods via public transit service. Indicators summarize accessibility to job as well as accessibility by workers, households and population. Coverage is limited to metropolitan regions served by transit agencies that share their service data in a standard format called GTFS . The Access to Jobs and Workers Via Transit - Technical Documentation and User Guide (PDF) (28pp, 1.7MB, About PDF) includes a full list of those areas. Figure 2 shows one indicator from this dataset mapped for the Washington DC metropolitan region.
