Highway Capacity Manual 2000

The Transportation Research Board’s (TRB’s) “Highway Capacity Manual” (HCM) provides a collection of state-of-the-art techniques for estimating the capacity and determining the level of service for transportation facilities, including intersections and roadways as well as facilities for transit, bicycles, and pedestrians. HCM 2000 represents a significant revision and expansion of the material provided in previous editions (1950, 1965, and 1985 with updates in 1994 and 1997). The manual has grown from 14 to 31 chapters. These chapters are divided into five parts: (I) Overview, (II) Concepts, (III) Methodologies, (IV) Corridor and Areawide Analyses, and (V) Simulation and Other Models. Parts I and III contain information that corresponds to the contents of previous editions. Part II provides concepts and estimated default values for use in planning-level analytical work. Part IV presents computational techniques and general analysis guidelines for corridor and areawide analyses. Part V offers background and information on alternative models that may be appropriate for systemwide or more complex analyses.
