About the HCM Reference Guide

The Highway Capacity Manual Reference Guide is intended to provide simple explanations and applicable guidance for use in typical highway capacity analysis tasks. Some methodologies in the Manual can be quite complex and contain many computations that can be misleading or misunderstood – which is where the guidance becomes most beneficial.

This document does not intend to repeat the HCM procedures themselves but to provide key insights to critical parameters and their effects on results that would be especially useful in reviews.
