We desired to understand how legal tools protect public health by regulating the location and density of alcohol, tobacco, firearms, and fast food retail outlets. We reviewed the literature to determine how land use regulations can function as control tools for public health advocates. We found that land use regulations are a public health advocacy tool that has been successfully used to lessen the negative effects of alcohol retail outlets in neighborhoods. More research is needed to determine whether such regulations are successful in reducing the negative effects of other retail outlets on community health.

We sought to synthesize evidence of the health effects of construction of new roads by systematically reviewing observational studies of such effects. We included and critically appraised 32 studies. The review suggested that out-of-town bypasses decrease injuries on main roads through or around towns, although more robust evidence is needed on effects on secondary roads. ⋯ Out-of-town bypasses reduce disturbance and community severance in towns but increase them elsewhere. Major urban roads increase disturbance and severance. More robust research is needed in this area, particularly regarding effects of new roads on respiratory health, mental health, access to health services, and physical activity.

Promoting safe walking and cycling to improve public health: lessons from The Netherlands and Germany.
We examined the public health consequences of unsafe and inconvenient walking and bicycling conditions in American cities to suggest improvements based on successful policies in The Netherlands and Germany. ⋯ A wide range of measures are available to improve the safety of walking and cycling in American cities, both to reduce fatalities and injuries and to encourage walking and cycling.

Some claim that car-dependent cities contribute to obesity by discouraging walking and bicycling. In this article, we use household activity data from the San Francisco region to study the links between urban environments and nonmotorized travel. ⋯ Built-environment factors exerted far weaker, although not inconsequential, influences on walking and bicycling than control variables. Stronger evidence on the importance of urban landscapes in shaping foot and bicycle travel is needed if the urban planning and public health professions are to forge an effective alliance against car-dependent sprawl.
