Highway Capacity Manual 2010 1. INTRODUCTION VOLUME 1: CONCEPTS The Highway Capacity Manual 2010 (HCM) is the fifth edition of this fundamental reference document. Like its predecessors, the HCM 2010 has been significantly revised to incorporate the latest research on highway capacity and quality of service. It has also been substantially reorganized. These changes continue the HCM’s evolution, keeping the manual in step with its users’ needs and present times. 1. HCM User’s Guide 2. Applications 3. Modal Characteristics 4. Traffic Flow and Capacity Concepts 5. Quality and Level-of-Service Concepts 6. HCM and Alternative Analysis Tools 7. Interpreting HCM and Alternative Tool Results 8. HCM Primer The 1950 HCM 9. Glossary and Symbols (1) was the first document to quantify the concept of capacity for transportation facilities and focused almost entirely on that subject. This focus was in response to the rapid expansion of the U.S. roadway system after World War II and the need to determine lane requirements for the Interstate highway system and the roads that provided access to it. The manual was designed to be “a practical guide by which the engineer, having determined the essential facts, can design a new highway or revamp an old one with assurance that the resulting capacity will be as calculated.” The focus on design continued in the 1965 HCM (2), but the level‐of‐service (LOS) concept was also introduced with this edition, along with a chapter on bus transit. The HCM permitted the “determination of the capacity, service volume, or level of service which will be provided by either a new highway design, or an existing highway under specified conditions.” The 1985 HCM (3) was another significant step in the evolution of the HCM. It further refined the concept of LOS and incorporated the results of several major research projects performed since the publication of the 1965 HCM. The target audience was broadened through the addition of chapters on pedestrians and bicycles and an expansion of the transit chapter. A substantial increase in the volume and breadth of material occurred with the publication of the HCM2000 (4). The intent of the manual was “to provide a systematic and consistent basis for assessing the capacity and level of service for elements of the surface transportation system and also for systems that involve a series or a combination of individual facilities.” The HCM 2010 has added much new material from research projects completed since the publication of HCM2000 and has been reorganized to make its contents more accessible and understandable. The reorganization is also intended to encourage analysts and decision makers to consider all roadway users, as well as a broader range of performance measures, when they assess transportation facility performance. Chapter 1, HCM User’s Guide, is the starting point for learning how to use this edition of the HCM. This chapter presents the purpose, objectives, intended use, and target users of the HCM 2010; describes the contents of each of the four volumes that make up the HCM; summarizes the major changes that have been made to HCM2000 methodologies; and mentions some of the important companion documents to the HCM. The remainder of Volume 1 presents the fundamental information with which users should be familiar before starting to apply the manual. Chapter 1/HCM User’s Guide Page 1-1 Introduction December 2010
