The presenters are Dr. Lawrence Frank, President of UD4H, and Eric Fox, Senior Planner at UD4H, John Thomas, Division Director at the Offices of Sustainable Communities at the U.S. EPA, Dr. David Berrigan, a Program Director at the Health Behaviors Research Branch at the National Cancer Institute and Kim Anderson, Senior Advisor at Regional Government Services (RGS).
Originally released in 2013, the SLD is a census block group-level database with a series of built environment and transportation access metrics comprising 5 core domains: 1) Density, 2) Diversity, 3) Design, 4) Transit and 5) Accessibility. The SLD is a well-known data resource used by federal agencies, planners, practitioners, researchers and community groups and other non-governmental organizations seeking a range of built environment metrics applicable for any region in the country.
The new SLD is based on:
Expanded transit coverage:
More recent General Transit Feed Specification (GTFS) data
Transit agencies included in the SLD more than doubled - now 573 agencies
Transit data now available for over 130 more regions
Regions with partial coverage before now have complete transit service coverage
Integrated more recent fixed-guideway transit stops for new rail lines and extensions
The latest updated demographic and employment data from the U.S. Census Bureau
Enhanced measures of auto and transit accessibility using traffic congestion weights
Expanded measure coverage for Alaska, Hawaii, Puerto Rico and the U.S. overseas territories (where data available)
