Specifications include, but are not limited to: Developing a 10-year prioritized program of research—a research roadmap—that will provide a broad overview of highly relevant research needs at the intersection of transportation and public health in the United States. The roadmap will also identify research that will provide evidence to support practical and useful information, and implementable tools, for state DOTs and their transportation partners to use to integrate public health considerations at all levels of their agencies’ decision-making. Accomplishment of these objectives will require input from both the transportation and public health sectors. The roadmap should: -Clearly describe a broad set of research topics and initiatives based on identified gaps in knowledge and practice that will advance the knowledge and capabilities of transportation decision-makers, and include a discussion of the relevancy of the proposed research agenda to state DOTs, regional planning organizations, and public health agencies. -Include a focus on under-researched areas. -Consider the level and timing at which transportation agencies make decisions or take actions that contribute to improved health outcomes, and their related implementation barriers and opportunities.
