Cover format is 3-ring binder. HCM 2000 (metric units) is a completely revised, updated, and expanded edition that reflects the results of a multiyear, multimillion-dollar research effort by NCHRP, FHWA, TCRP, and TRB. TRBs Committee on Highway Capacity and Quality of Service oversaw development of the manual. The content and format of HCM 2000 incorporate major changes and improvements in analysis methodologies. New to HCM 2000 are a chapter on interchange ramp terminals, sections on the planning uses of the material, and a discussion of the appropriate use of simulation models. Other features include: more than 1,100 pages with a detailed index; separate editions for U.S. customary and metric units; separate presentations of concepts and procedures; expanded scope, from individual points (signals) and segments (freeways) to facility, corridor, and area wide analysis; and expanded coverage of facility types and congestion levels. HCM 2000 also is available on a CD-ROM, which adds tutorials, narrated example problems, explanatory videos, navigation tools, and hyperlinks between sections.
