  • Abstract:
    The term “livability” has been finding its way into policy discussions in the United

    States steadily over the last decade. Organizations like the American Planning

    Association (APA) and AARP have been concerned about livable neighborhoods and

    communities in the United States for decades (Pollack, 2000; Bosselmann and

    Macdonald, 1999), but the influence of livability on federal policy accelerated

    rapidly in 2009 when USDOT Secretary Ray LaHood began to use the term

    extensively including as a potential selection criteria in transportation projects

    (LaHood, 2009). Some transportation professionals and communities hope that a

    new selection process will replace travel -time reduction as the top priority dictated

    by the 2005 Safe, Accountable, Flexible, Efficient Transportation Equity Act

    (SAFETEA-LU), with a more multi-modal, multi-faceted measurement which

    includes environmental protection, economic development, and community

    improvement in general. It is possible that livability, and methods that measure it,

    will be a fundamental part of the next surface transportation program. USDOT‟s

    new initiatives dovetail with a new partnership with HUD and EPA, which seeks to

    combine the agencies‟ resources to meet shared goals centered on the concept of

    livability.

    Livability is a concept that relates to many characteri stics of a community or

    neighborhood, and lends itself to a multitude of planning and maintenance

    considerations for physical infrastructure. As evidenced by the USDOT’s

    attachment to the term, its relevance is critical in the planning and evaluation of

    our transportation systems. A new attitude in the transportation community

    regards transport systems as a “public good” and the users of those systems as

    “consumers”. Under this framework, it becomes the responsibility of planners to

    meet the market’s demand for mobility and access.

    The research community tends to agree that livability may be defined differently for

    different groups – urban and rural, young and old. While many different definitions

    of livability exist, there is growing agreement that it is best defined by the users, or

    “consumers”, of the system. This assumption makes it critical to understand what

    users of our transportation system value, and then to develop methods that can

    assimilate those values into measures of progress and success (Miller, 2010). In this

    way, the concept of livability dictates the research methods needed to inform policy.
