Willingness to Pay for High-Occupancy Toll Lanes Academic Article uri icon

abstract

  • This research examined the willingness of travelers to pay for travel time savings (TTS) on the I-394 MnPASS express lanes in Minneapolis, Minnesota, and the I-15 express lanes in San Diego, California. The findings from both facilities indicate that many travelers are willing to pay a toll for a small TTS. The revealed preference values of time for the I-394 paying customers averaged $73/h in the morning and $116/h in the afternoon. Travelers on the I-15 express lanes received slightly higher TTS than on the I-394 and typically had a lower willingness to pay. Their revealed preference values of time averaged $49/h in the morning and $54/h in the afternoon. On the basis of the magnitude of these values, it is likely that travelers are paying for more than just TTS, possibly travel time reliability also. This finding means that these lanes likely have added value to travelers beyond time savings. The variability of the dynamic toll prices on the I-394 MnPASS express lanes in Minnesota and the I-15 express lanes in San Diego was also examined. Toll rates during the morning and afternoon peak hours varied considerably, with tolls ranging from $0.50 to $8.00. Conversely, off-peak times showed little to no variation. These trends were similar for different days of the week, and even from year to year. These trends were common across both I-394 and I-15 express lanes, although more variation was found on I-15. Tolls varied little during off-peak periods.
