Transportation decisions should facilitate and account for freight flows, but analysts lack the tools needed to evaluate them. Incorporation of truck analysis into the Highway Capacity Manual (HCM) would help transportation agencies address the freight and highway needs of their community, region, state, and nation. This report presents capacity and level-of-service techniques that (1) improve transportation agencies’ abilities to plan, design, manage, and operate streets and highways to serve trucks and (2) better evaluate the effects of trucks on other modes of transportation and vice versa. The research team for National Cooperative Freight Research Program (NCFRP) Project 41 took a comprehensive approach to addressing the issue. In addition to a literature review, federal, state, regional, and local agencies were contacted to document the state of the practice. Carriers and shippers were interviewed to determine the critical factors that affect logistical decisions. Based on the insights from these activities, the research team developed a truck level-of- service framework. This framework was refined through two workshops with a wide variety of public transportation agency staff to ensure that it would be useful in their work, particularly in evaluating the impacts of system improvements on goods movements. The utility of this framework was demonstrated through the development of three case studies. The research team then collected field data and calibrated simulation models on freeways and arterials. These models were used to develop improved methods of estimating performance measures for trucks and other vehicles. The report includes several recommendations for improvements to the HCM, and these are being considered in National Cooperative Highway Research Program (NCHRP) Project 03-115, which is updating the HCM for expected publication in 2015.
