Abstract
Participants from California cities and counties participated in a 1-year local technical assistance program for learning, applying, and evaluating the procedures in the 1997 update to the Highway Capacity Manual (HCM) for the analysis of signalized and unsignalized intersections. Training and technical assistance were provided to the participants on the practical application of the 1997 HCM procedures. Field studies and HCM applications were undertaken at 28 signalized and unsignalized intersections by 25 first-time HCM users in 22 cities and counties. The findings from the project evaluation indicate that the project was highly successful and that similar educational and application experiences should be undertaken for new users of the HCM 2000 in other states. The assessment of the analysis techniques and software will aid the Committee on Highway Capacity and Quality of Service in better understanding the needs and desires of users for future editions of the HCM as well as software developers in better meeting the needs of users.
