Quality of travel, usersвЂ™ perceptions of travel on a transportation facility or service with respect to their expectations.

Quantity of travel, the magnitude of use of a transportation facility or service.

Providing mobility for people and goods is transportationвЂ™s most essential function. HCM has evolved over the years to keep pace with the needs of its users and society, as the focus of surface transportation planning and operations in the United States has moved from designing and constructing the Interstate highway system to managing a complex transportation system that serves a variety of users and travel modes.

These changes are designed to keep the manual in step with its usersвЂ™ needs and present times. The objective is to help practitioners applying HCM methods understand their basic concepts, computational steps, and outputs. The Sixth Edition incorporates the latest research on highway capacity, quality of service, Active Traffic and Demand Management, and travel time reliability and improves the HCMвЂ™s chapter outlines. In its current form, it serves as a fundamental reference on concepts, performance measures, and analysis techniques for evaluating the multimodal operation of streets, highways, freeways, and off-street pathways. The sixth edition incorporates the latest research on highway capacity, quality of service, active traffic and demand management, and travel time reliability.Now available to order from the TRB Bookstore, the Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis (HCM) provides methods for quantifying highway capacity. The final version, published as the Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis, or HCM 2016, or HCM6, was released in October 2016 and is available from TRB.

The new and revised material was scheduled to be published as a 2015 interim update of the HCM 2010, known as the HCM 2015 Update. In 2013 the Transportation Research Board contracted the development of a major update to the 2010 Highway Capacity Manual. The fifth edition HCM 2010 was the culmination of a multiagency effort-including TRB, American Association of State Highway and Transportation Officials (AASHTO), and Federal Highway Administration-over many years to meet the changing analytical needs and to provide contemporary evaluation tools. The following editions were published by the Transportation Research Board in 1965, 1985, 2000, 20. It was the result of a collaborative effort between the Transportation Research Board (TRB) and the Bureau of Public Roads, predecessor to the Federal Highway Administration. The first edition of the Highway Capacity Manual was released in 1950 and contained 147 pages broken apart into eight parts. There are more than six decades of research behind the HCM. The current version, the Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis, or HCM 2016, or HCM6, was released in October 2016 The sixth edition incorporates the latest research on highway capacity, quality of service, active traffic and demand management, and travel time reliability. The HCM has been a worldwide reference for transportation and traffic engineering scholars and practitioners, and also the base of several country specific capacity manuals. There have been six editions with improved and updated procedures from 1950 to 2016, and major updates to the HCM 1985 edition, in 1994, 19. It contains concepts, guidelines, and computational procedures for computing the capacity and quality of service of various highway facilities, including freeways, highways, arterial roads, roundabouts, signalized and unsignalized intersections, rural highways, and the effects of mass transit, pedestrians, and bicycles on the performance of these systems. The Highway Capacity Manual ( HCM) is a publication of the Transportation Research Board of the National Academies of Science in the United States.
