Abstract:

High Occupancy Toll (HOT) facilities are effective tools for managing demand and mitigating congestion where construction to expand roadway capacity is not feasible. This paper evaluates paying Single Occupancy Vehicles’ (SOV) responses to toll rates. Due to the unique features of HOT facilities— dynamic toll rates and multiple access points—drivers’ reactions to the change in HOT lane toll rates can differ substantially from traditional toll road drivers’ reactions. This is especially true for paid SOV drivers. This study used toll and traffic data from SR-167 in Washington State in 2008 and 2010. Logistic regression models were used to evaluate the influence of toll rate, volume, speed, and speed reliability on the percentage of paid SOVs in the HOT lane. Results show that both HOT and general-purpose traffic conditions impact SOVs’ choices. Speed, speed reliability, and traffic volumes in the general-purpose lanes are all associated with the percentage of paid SOVs using the HOT lane. Toll rate is only significant for the year 2010, and a ramp-up effect in use is found from the HOT lane’s 2008 opening year to 2010. SOV drivers’ reactions to dependent variables in 2008 differ significantly from reactions found in 2010. This study provides critical information for understanding the factors affecting drivers’ HOT lane use choices, as well as insights into the design of tolling schemes at different stages of a HOT facility.
