Transportation Choices for Sustainable Communities Research and Policy Institute (TCSC) is a 501 (c)(3) nonprofit corporation founded in order to advance understanding of sustainable transportation as an essential component of livable communities and cities. The TSCS Institute studies and evaluates the ways and means of creating more life-affirming transportation systems and disseminates this information to both the public and decision makers. It also partners and collaborate with academics and community representatives, as well as city planners, engineers, architects, public health planners, and members of allied professions. The aim of our work is to illuminate the central role that sustainable transportation plays in the vibrancy of communities. In pursuing these aims, the Institute researches and informs on a variety of policies and programs, including non-motorized transport, public transportation, traffic calming, street design, transit-oriented development, travel safety, public health, environmental quality, urban design and smart growth.
