Service Description: Full Metadata The Smart Location Database (SLD) characterizes the built environment within every U.S. Census block group using several variables that are demonstrated in the transportation research literature to have an effect on residential travel behavior. These variables are all related to factors known as the five Ds: Density (of population, housing, or jobs), land use Diversity, urban Design (intersection density), Destination accessibility, and Distance to transit. See technical report for details. See data dictionary for description of variable names. Both available here: https://edg.epa.gov/data/Public/OP/SLDv02_docs.zip
