Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis

Now available to order from the TRB Bookstore, the Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis (HCM) provides methods for quantifying highway capacity. In its current form, it serves as a fundamental reference on concepts, performance measures, and analysis techniques for evaluating the multimodal operation of streets, highways, freeways, and off-street pathways. The Sixth Edition incorporates the latest research on highway capacity, quality of service, Active Traffic and Demand Management, and travel time reliability and improves the HCM’s chapter outlines. The objective is to help practitioners applying HCM methods understand their basic concepts, computational steps, and outputs. These changes are designed to keep the manual in step with its users’ needs and present times.
