Welcome to the HCM 2010 Major Update Development Website.
The purpose of NCHRP Project 03-115: Major Update of the 2010 Highway Capacity Manual (HCM) is to support, to the extent practical, the performance measure requirements of MAP-21, travel time reliability analysis, and ATDM strategy evaluation, while maintaining the HCM’s support of more traditional system planning, design, and operations activities. HCM chapters will need to be revised to incorporate the research related to these and be adopted by the Transportation Research Board’s Committee on Highway Capacity and Quality of Service (HCQS).
This website is intended to serve as a means of communication between the production team, the oversight panel, and committee reviewers during the development of the HCM 2010 Major Update. Its principal purpose is to provide all interested parties a central source for up-to-date information about the project. A significant section of the site is devoted to posting draft HCM chapters and other research products for review.
