OTREC was used as a UTC Spotlight on livable communities. Livable communities are places that achieve economic prosperity, environmental quality, and social equity -the "three Es" of sustainability. In terms of transportation, they are places where transportation modes other than driving are viable for activities such as walking or biking to school. The built environment of a livable community yields lower greenhouse gas emissions, reduced dependence on foreign oil, and improvements in public health (which are associated with lower health care costs). Interest in livability has been accelerated recently by an increased focus on the relationship between urban form and transportation. The childhood obesity epidemic has fueled interest in events such as "bike and walk to school day" across the country.
Several OTREC researchers who are currently involved in livability research include: Dr. Yizhao Yang's who's research examines whether and how getting to school influences where parents decide to live; Nico Larco's and his investigation into Sustainable Suburbs; and Dr. Marc Schlossberg and his extensive development of participatory mapping tools for accessing walkable communities.
