TRB’ National Cooperative Highway Research Program (NCHRP) has issued a request for proposals to update the 2010 Highway Capacity Manual to support, to the extent practical, the performance measure requirements of Moving Ahead for Progress in the 21st Century Act, travel time reliability analysis, and active transportation and demand management strategy evaluation, while maintaining its support of the more traditional system planning, design, and operations activities. The project would have a target publication date within 2015. Proposals are due by August 13, 2013.
