The American Public Health Association (APHA) developed several new resources to help public health and transportation professionals understand the connection between health and transportation.  One is an on-line toolkit with fact sheets, communications and outreach materials, and background data and resources; another is the four-part webinar series on "What Healthy Communities Need from their Transportation Networks" (archived online); and a third is the report entitled “The Hidden Health Costs of Transportation,” which addresses the ways in which transportation systems can contribute to or hinder progress toward improving public health.
