This report summarizes the top 10 lessons learned from the Mobility Monitoring Program with respect to using archived traffic detector data for monitoring highway performance (e.g., traffic congestion and travel reliability). The Mobility Monitoring Program started in 2000 with archived freeway detector data from 10 cities. In 2004, the Program has grown to include nearly 30 cities with about 3,000 miles of freeway. In the first four years of the Program, the project team has gained valuable experience in the course of gathering archived data from State and local agencies for national congestion monitoring. The top 10 lessons learned are centered on these three general areas: analytical methods, data quality, and institutional issues. We believe these lessons learned will be instructive to the Federal Highway Administration (FHWA) as they continue to develop a national congestion monitoring program, as well as being useful for State and local agencies engaged in developing congestion monitoring capabilities. |
