ABSTRACT
Health organizations and foundations are increasingly calling for new approaches that involve changes in the built environment to address complex health problems. Community designs that encourage integrating walking and cycling into daily routines as a way of life are seen as potential solutions to the obesity epidemic the U.S. faces today. Yet, the net health effect that results from changes in the built environment aimed at improving the walkability and bikeability of communities is not known today. For instance, none of the empirical work to date has examined the extent to which increases in physical activity can result in higher exposures to hazards such as air pollution or traffic injuries. The built environment affects our lives in many ways, ranging from its influence on behavior and on the quality of the natural environment, to the good functioning of society and equitable treatment of its members – all of which result in an impact on our health and quality of life.
This paper lays the framework for conducting a risk assessment in a pedestrian-oriented environment. Theoretical and empirical findings that link community design to behavioral and health endpoints are reviewed. The risk assessment will use factors derived from the literature to quantify these links. Some relationships are well established, while as for others, the literature will be synthesized to produce factors that represent the best state of current knowledge on the association in question. In both cases a thorough uncertainty analysis will be performed. A case study will be used to carry out the risk analysis, with hypothetical scenarios of changes in the built environment.

PRINCIPLES OF “PEDESTRIAN-ORIENTED” DESIGNS:
Destinations are made more accessible to pedestrians by shortening distances from home to retail or employment, and by creating a more “human scale” environment. This involves creating: mixed, accessible, and dense land uses; dense and efficient street network (connected streets, grid-like pattern, small block sizes, continuous sidewalks, etc.); transit network; human-friendly neighborhood microscale design with attention to building orientation (e.g. shortened set-backs), parking location (e.g. on street), landscaping (e.g. vegetative street buffers, trees for shade), pedestrian amenities (e.g. street lighting, benches) etc.
