QUANTIFYING CONGESTION. VOLUME 2: USER'S GUIDE

This User's Guide describes how to measure congestion in the field (including determining the number of samples that should be collected), presents methods for estimating congestion when field measurement is not possible or practical, and describes different ways to present congestion measures so that they are understandable to policy makers and the public. It will be useful to those responsible for measuring or estimating congestion or presenting their findings to the public and policy makers. It includes a summary of the information in the companion final report (NCHRP Report 398, Volume 1).
