Managed Lanes: Highway facilities or a set of lanes where operational strategies are proactively implemented and managed in response to changing conditions.

High Occupancy Vehicle (HOV) Lanes: Facilities that typically do not require a toll and are restricted to vehicles carrying more than one occupant per vehicle.

High Occupancy Toll (HOT) Lanes: High Occupancy vehicles pay either no toll or reduced tolls to use the reserved lanes, while single-occupancy vehicles pay tolls on a value-priced basis.

Electronic Tolling: An automated toll collection system deploying various communications and electronic technologies to support the collection of tolls at toll collection points, express lanes and open road toll collection points. Collectively, the application of these technologies increases system throughput, enhances safety, and reduces environmental impacts.

Congestion Pricing: A traffic management tool whereby drivers are charged a fee that varies with the level of traffic on a congested roadway. Congestion pricing is designed to allocate roadway space, a scarce resource, in such a manner to provide free-flow travel for its users. Also known as "congestion-relief tolling."
