DESCRIPTION OF TOLL CONCEPTS

Description of Toll Concepts

The arrangement of toll points on a facility to collect tolls. A toll point is a place where tolls are collected, either with a toll plaza, or at an Open Road Toll (ORT) toll zone without a cash plaza.

 

Toll Point Type Description Examples
Closed System
An arrangement of toll points on a facility to ensure that all vehicles pay some toll amount for use of the facility.
Closed TripBased Toll System Entry-Exit (“Ticket”) System An arrangement of toll plazas at every facility entrance and exit. This arrangement enables the measurement of trip length by recording facility entry on paper tickets (or an electronic toll record) and collecting paper tickets or electronically recording the exit location. Entry-exit systems can work with ETC as well as with tickets. PA Turnpike Mainline, Ohio Turnpike, Indiana Toll Road, NJ Turnpike. Mass Pike (I-90) was originally a ticket system toll road.
AET EntryExit System An arrangement of toll zones without toll plazas at every facility entrance and exit, to measure trip length as recorded in the electronic toll system. Toronto 407-ETR, portions of the New York State Thruway
AET Mainline System An arrangement of toll zones without toll plazas between interchanges. The toll system collects the toll zone data to determine a trip entry and exit – and thus trip length. Mass Pike (I-90), Virginia Express lanes (I-95, I-395, I-495)
Closed Barrier Toll System AET Mainline System An arrangement of toll zones without toll plazas between interchanges, with discrete toll rates at each toll zone. Illinois Route 390, MDTA MD-200.
Closed Barrier Plaza System An arrangement of mainline and ramp toll plazas and/or toll zones with discrete toll schedules at each location, arranged such that every possible trip incurs at least one toll. Illinois Tollway (except Route 390), TCA, E-470, NTTA and HCTRA
Open System
Not a closed system.
Open Barrier System An arrangement of (typically mainline) toll points with discrete toll schedules for each location. Open barrier systems do not capture all potential trip origins and destinations and so allow some toll-free travel. An open barrier system may use ORT toll zones or toll plazas. Delaware Turnpike, MDTA I-95 (JFK Memorial Highway).
