The section of California State Route 91 (SR 91) containing the express lanes is located between the SR 91/SR 55 junction in Anaheim and the Orange/Riverside County Line. Key elements of the data set are available on-line at. The study also produced an extensive data set which is itself an important study product, since it provides opportunities for other researchers to explore aspects of the express lanes which are beyond the scope of the current study. The current report contains findings through mid-1999, supplementing a previous "final report" issued May 1998, which presents impacts through June 1997. Data analysis included calibration of models of the route (toll/non-toll), vehicle occupancy, transponder acquisition, and time-of-day choices of commuters as well as estimation of air pollution emissions.
Data collection included traffic measurements, vehicle occupancy counts, transit ridership data, and comprehensive travel surveys with current and former commuters. This report documents more than five years of field observations, including about a year and a half of observations to establish baseline conditions before the facility opened. Some of these insights pertain to implementing value-pricing projects in other locations. As the first practical application of value pricing in the United States, this project provides many important insights, both technical and institutional. DOT-sponsored study to identify the impacts of the value-priced express lanes which opened on Decemin the median of State Route 91 in Orange County, Ca. This is the follow-up final report for a Caltrans and U.S.
