This study estimates a discrete choice model for mode plus route plus time choice, subdivides the population according to empirically formed choice sets, and finds systematic variations among four choice set groups in user preferences for price managed lanes. This study addresses this problem by revealing a previously overlooked connection between choice set and choice behavior. As the first practical application of value pricing in the United States, the State Route 91 express lanes provide many important insights, both technical and institutional, some of which are relevant to the implementation of value-pricing projects in other locations.ĭue to recent pricing studies that have revealed substantial variability in values of time among decision makers with the same socioeconomic characteristics, there is substantial interest in modeling the observed heterogeneity. Findings are presented on traffic trends, toll lane use, travelers' responses to changing congestion and tolls, shifts in ridesharing and transit use, shifts in trip purpose, differences associated with income and other demographics, public opinion, collision experience, and the results of choice and emissions modeling. The corresponding data analysis included the calibration of choice models of route, occupancy, transponder acquisition, and time-of-day behavior of commuters and the estimation of air pollution emissions.

Data collection, covering about a year and a half of observations to establish baseline conditions before opening day, included traffic measurements, vehicle occupancy counts, transit ridership, and comprehensive travel surveys of current and former commuters.

Recently over 5 years of field observations were concluded of the value-priced express lanes that opened December 27, 1995, in the median of State Route 91, in Orange County, California.
