For walk and transit accessibility, over what area are destinations included?

The accessibility modules measure access to destinations within a project area and a broader "access area" defined as a 50-kilometer buffer area around a project. Population, household, and employment counts in the access area are derived from census data at the block level. Employment data is sourced from U.S. Census Longitudinal Employer-Household Dynamics (LEHD) Origin-Destination Employment Statistics (LODES) data. Population and household data are derived from U.S. Census Decennial Census data.

See Walk and Transit Accessibility Analysis for further details on the destinations included.
