Transportation engineers have used editions of the Highway Capacity Manual (HCM) in their analyses for decades. The HCM is the fundamental reference for concepts, performance measures, and analysis techniques for evaluating the multimodal operation of streets, highways, freeways, and off-street paths. This 3-volume 7th Edition contains new information, including new planning-level methods for connected and automated vehicles; a completely revised procedure for analyzing two-lane highways; a new procedure for evaluating systems of freeways and arterials with queue spillback; and updated methodologies for pedestrian operations at uncontrolled and signalized crossings.
