Open road tolling (ORT), also called all-electronic tolling, cashless tolling, or free-flow tolling, is the collection of tolls on toll roads without the use of toll booths. An electronic toll collection system is usually used instead. The major advantage to ORT is that users are able to drive through the toll plaza at highway speeds without having to slow down to pay the toll. In some installations, ORT may also reduce congestion at the plazas by allowing more vehicles per hour/per lane.

Contents

The disadvantage to ORT is that it relies on the honor system to the extent that without the presence of toll booths there is typically no physical means of preventing drivers who have no intention of paying the toll from accessing the road. Toll operators refer to such toll evasion as "leakage." To deter such behavior, toll operators can employ tools such as high-definition cameras to identify violators, and leakage can be offset in part or whole by fees and fines collected against offenders. However, in many cases such enforcement is relatively limited (for example, targeting only commercial vehicles and other such flagrant and/or repeat offenders). Some toll operators prefer to simply write off leakage as an expense, especially if the costs associated with collection efforts are expected to exceed the additional tolls, fees and/or fines that will likely be collected, or alternatively allow vehicles that are privately operated and/or below a specified size and/or weight to access the toll road free of charge.[ citation needed ]

History

Many ETC systems use transponders like this one to electronically debit the accounts of registered cars without their stopping. FasTrak transponder.jpg
Many ETC systems use transponders like this one to electronically debit the accounts of registered cars without their stopping.

In 1959, Nobel Economics Prize winner William Vickrey was the first to propose a system of electronic tolling for the Washington metropolitan area. He proposed that each car would be equipped with a transponder. The transponder's personalized signal would be picked up when the car passed through an intersection and then relayed to a central computer which would calculate the charge according to the intersection and the time of day and add it to the car's bill. [1]

Norway has been the world's pioneer in the widespread implementation of this technology. ETC was first introduced in Bergen, in 1986, operating together with traditional tollbooths. [2] The first major deployment of an RFID electronic toll collection system in the United States was the TollTag system used on the Dallas North Tollway, implemented in 1989 by Amtech. [3] The first fully automated toll highway in the world, Ontario Highway 407, opened in Canada on June 7, 1997. [4] The highway managed to achieve this automation through the use of both RFID technology and automatic number-plate recognition. [5]

In September 1998, Singapore became the first city in the world to implement an electronic road toll collection system for purposes of congestion pricing. [6] Today there are many roads around the world using electronic toll collection technologies, and ORT has opened the feasibility to implement congestion pricing policies in urban areas.

Collection of tolls on open toll roads is usually conducted through either the use of transponders or automatic plate recognition, the vast majority of which utilizes an overhead gantry system above the road. While rarely used as the primary vehicle identification method, automatic number plate recognition is used on a number of different highway systems. Both methods aims to eliminate the delay on toll roads by collecting tolls electronically by electronically debiting the accounts of registered car owners without requiring them to stop.

Transponders

Transponders are a receiver-transmitter that will generate a reply signal upon proper electronic interrogation. Transponders are an adaptation of military identification friend or foe technology. Most current systems rely on radio-frequency identification, where an antenna at the toll gate communicates with a transponder on the vehicle via dedicated short-range communications (DSRC). Some early systems used barcodes affixed to each vehicle, to be read optically at the toll booth. Optical systems proved to have poor reading reliability, especially when faced with inclement weather and dirty vehicles.

Automatic number plate recognition

Automatic number plate recognition (ANPR) or an automatic license plate reader (ALPR) is a system that uses optical character recognition on images to read the license plates on vehicles. [7] While the technology is most commonly used by law enforcement for cataloging vehicle movements and traffic enforcement, [8] ANPR has also been used as a method of electronic toll collection. [9] ANPR can be used in conjunction with transponder systems. If a transponder is not detected on a vehicle, a system of cameras located at each junction logs the vehicle's unique identity and an invoice is mailed. [10] The use of ANPR reduces fraud related to cash transactions [11] or non-payment, [10] [ better source needed ][ non-primary source needed ] makes charging effective,[ clarification needed ] and reduces the amount of required manpower to enforce the toll road,[ citation needed ] but requires expensive computer software. [12]

However, ANPR usage raises questions over privacy and data protection. ANPR allows police to automatically compile vast databases of innocent road users' movements, thus invading their privacy. [13] Another concern is that the collected data can be abused by employees or stolen by computer hackers. This has led the police of Scotland to delete their collection of ANPR records in 2016. [12] As ANPR is a new technology, its use is often not tightly regulated; [13] it is unclear whether ANPR in Scotland complied with the UK data retention laws. [12]

<span class="mw-page-title-main">Electronic toll collection</span> Wireless system to automatically collect the usage fee or toll charged to vehicles

Electronic toll collection (ETC) is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. It is a faster alternative which is replacing toll booths, where vehicles must stop and the driver manually pays the toll with cash or a card. In most systems, vehicles using the system are equipped with an automated radio transponder device. When the vehicle passes a roadside toll reader device, a radio signal from the reader triggers the transponder, which transmits back an identifying number which registers the vehicle's use of the road, and an electronic payment system charges the user the toll.

E-ZPass is an electronic toll collection system used on toll roads, toll bridges, and toll tunnels in the Eastern, Midwestern, and Southern United States. The E-ZPass Interagency Group (IAG) consists of member agencies in several states, which use the same technology and allow travelers to use the same transponder on toll roads throughout the network.

<span class="mw-page-title-main">Barrier toll system</span> Method of collecting tolls on highways

A barrier toll system is a method of collecting tolls on highways using toll barriers at regularly spaced intervals on the toll road's mainline. Motorists are typically charged a flat-rate toll, unlike toll roads with a ticket system where the toll rate is determined by the distance traveled or number of exits passed. Some highways use coin-drop machines on toll plazas. For toll roads whose ramps have no toll plazas, it is possible to exit the toll road before the mainline toll plaza, use local streets to bypass it, then re-enter the highway via an interchange on the other side of the toll plaza. Thus it is possible to drive on some barrier toll roads while paying less or not paying at all; this is the basis of the "open" descriptor.

Oklahoma has an extensive turnpike system, maintained by the state government through the Oklahoma Turnpike Authority. All of Oklahoma's turnpikes are controlled-access highways. The majority have at least four lanes, though the Chickasaw Turnpike is two lanes.
