Empirical evidence from the Greater Toronto Area on the acceptability and impacts of HOT lanes

This paper describes a study on willingness to pay (WTP) and public acceptability for High-Occupancy/Toll (HOT) lanes using empirical evidence from Toronto, Ontario, Canada. From a stated preference survey of more than 250 drivers, we estimate mean willingness to pay values under various trip conditions and for various traveler characteristics. The study provides statistically significant evidence on the relationships between willingness to pay and the improvement in travel speeds in HOT lanes, the length of the trip, and the urgency of on-time arrival. Furthermore, our study confirms several literature findings from previous studies on the relationship between travelers' willingness to pay and income as well as prior experience with HOT lanes. Some of the findings are qualitatively validated on the basis of the observed travel behavior in choosing tolled facilities over untolled facilities during periods of heightened congestion and urgency.

► Adds to the literature on relationships between WTP and trip/driver characteristics.
► Develops an elasticity relationship between WTP and travel time savings.
► Contributes additional evidence on equity in road pricing projects.
► Demonstrates the potential for transit and carpooling to mitigate equity concerns.
► Makes revealed preference observations on driver behavior in various travel periods.
