摘要：

Operational analyses provided within the Highway Capacity Manual 2010 (HCM), also referred to as highway capacity analyses, estimate various performance measures such as queues, delays, and travel times as functions of the expected demand and geometry. They also estimate the level of service (LOS) as a function of one or more of these performance measures. Bicycle LOS analysis in the 2010 HCM is performed at various geographic levels within an urban street setting. The HCM provides procedures to assess LOS for signalized intersections, links, segments, facilities, and off-street bicycle and shared-use path. Pedestrian LOS analysis in the 2010 HCM is performed for the same types of geographic levels as for bicycle analysis. In addition, the HCM provides street corner pedestrian storage and crosswalk circulating capacity checks for pedestrians at a signalized intersection. Chapter 23 of the HCM provides methods for analyzing off-street pedestrian and bicycle facilities. Three situations are considered. The first situation is a pedestrian-only facility, such as a pedestrian path, stairway, overpass, or underpass, with LOS determined by the space available to the average pedestrian. Work is currently well underway to prepare a major update to the HCM 2010 and to integrate the results of several Cooperative Research Program and Federal Highway Administration research projects completed since the last edition. It should be recognized that the HCM focuses on traffic operational quality, and thus its methods estimate performance measures related to that aspect of transportation.
