Volume 4 of the Highway Capacity Manual has been revamped to allow ALL users to have access to this important resource. What is Highway Capacity Manual Volume 4? The HCM was divided into multiple volumes as part of the 2010 Manual production. Volumes 1-3 are part of the printed Manual. Volume 4 is an online resource that provides a wealth of. This release of the Highway Capacity Software (HCS7) includes updated modules to implement the Highway Capacity Manual 6th Edition (HCM6) procedures for Signalized Intersections, Urban Streets, Alternative Intersections, Roundabouts, Freeway Facilities, Basic Freeway Segments, Freeway Weaving Segments, Freeway Merge & Diverge Segments,. Highway Capacity Software Developed and maintained by McTrans o Originally founded by the FHWA in 1986 as the Center for Microcomputers in Transportation (McTrans) o Now a full-service software support center, associated with the University of Florida HCS 2010 o HCS 2010 implements the procedures defined in the Highway Capacity Manual.
The Highway Capacity Manual (HCM) is a publication of the Transportation Research Board of the National Academies of Science in the United States. 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.[1][2]
There have been six editions with improved and updated procedures from 1950 to 2016, and major updates to the HCM 1985 edition, in 1994, 1997 and 2015.[1][3][2] 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. 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.[2]
History[edit]
There are more than six decades of research behind the HCM. The first edition of the Highway Capacity Manual was released in 1950 and contained 147 pages broken apart into eight parts. 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.[1]
The following editions were published by the Transportation Research Board in 1965, 1985, 2000, 2010 and 2016. 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.
In 2013 the Transportation Research Board contracted the development of a major update to the 2010 Highway Capacity Manual. 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.[4][5] 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.[2] The sixth edition incorporates the latest research on highway capacity, quality of service, active traffic and demand management, and travel time reliability.[2]
