Open road tolling

From Wikipedia, the free encyclopedia

Open road tolling (ORT) is the collection of tolls on toll roads without the use of toll booths. 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^{[citation needed]} installations, ORT may also reduce congestion at the plazas by allowing more vehicles per hour/per lane. The disadvantage to ORT is the possibility of "leakage"; that is, "violators" who do not pay. Leakage may either be written off as an expense by the toll operator, or offset in part or whole by fees and fines collected against the violators.

Tolls are typically collected using RFID systems like FasTrak, Fast Lane, I-Pass, or E-ZPass. Some systems may also use license plate images as payment. One example of a system that collects tolls with plate images is the 407 ETR in Canada. To date, license plate bases systems have struggled somewhat with accuracy and customer service issues.^{[citation needed]} For example, the 407 ETR recently settled a lawsuit related to potential incorrect charges on the system.^[1]

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, as already implemented in Singapore, London, Oslo, Stockholm and other cities. They are currently in usage throughought the highway system in Santiago, Chile and it is known as the TAG.
