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. While rarely used as the primary vehicle identification method, automatic number plate recognition is used on a number of different highway systems. Today there are many roads around the world working with electronic toll collection technologies, and ORT has opened the feasibility to implement congestion pricing policies in urban areas.Ĭollection 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. In September 1998, Singapore became the first city in the world to implement an electronic road toll collection system for purposes of congestion pricing. The highway managed to achieve this automation through the use of both RFID technology and automatic number-plate recognition. The first fully automated toll highway in the world, Ontario Highway 407, opened in Canada on 7 June 1997. 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. ETC was first introduced in Bergen, in 1986, operating together with traditional tollbooths. Norway has been the world's pioneer in the widespread implementation of this technology. 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. He proposed that each car would be equipped with a transponder. In 1959, Nobel Economics Prize winner William Vickrey was the first to propose a system of electronic tolling for the Washington metropolitan area.

Many ETC systems use transponders like this one to electronically debit the accounts of registered cars without their stopping
#OPEN ROADS MEANING FREE#
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. However, in many cases such enforcement is relatively limited (for example, targeting only commercial vehicles and other such flagrant and/or repeat offenders). 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.

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. In some installations, ORT may also reduce congestion at the plazas by allowing more vehicles per hour/per lane. 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. An electronic toll collection system is usually used instead. 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.
