Abstract:

In recent years, high-occupancy-toll lanes have emerged as an increasingly popular alternative to high-occupancy-vehicle lanes for solving the problems of traffic congestion and air pollution. However, the existing literature on the use of high-occupancy-toll lanes has attended much to their impacts to the neglect of their determinants. An understanding of why people choose to use high-occupancy-toll lanes will shed light on policy decisions concerning high-occupancy-toll lane investments and developments. To fill this void, this study examines the determinants of high-occupancy-toll lane use with the first comprehensive survey data on the State Route 91 Express Lanes in California and multivariate logistic regression models. The results show that controlling for other variables, household income, vehicle occupancy, commute trip, and age are important predictors of high-occupancy-toll lane use, but gender, trip length, trip frequency, and other household characteristics make no significant differences in high-occupancy-toll lane use. Moreover, contrary to the conventional wisdom, work-to-home trips are found to be more likely to use high-occupancy-toll lanes than home-to-work and other trips. These findings provide some useful indications for the implementation of high-occupancy-toll lanes and future research.
