A phenomenon where the signal from a transponder is picked up by the reader or Roadside Unit (RSU) in a toll lane other than the queue the vehicle is traveling in. This can result in toll being applied to the wrong vehicle, double charges or lost transactions.

Cordon (Area) Tolls

*UPDATED* Cordon tolls are fees paid by motorists to drive into a designated area defined by a line that encloses to tolling area, often a city center.

Connected Vehicle

Connected Vehicle Program - The U.S. DOT Research and Innovative Technology Administration (RITA) \ ITS Joint Program Joint Program Office (ITS JPO) is the major sponsor of the Connected Vehicle program. Connected Vehicle focuses on localized Vehicle-to-Vehicle, Vehicle-to-Infrastructure and Vehicle-to-Device Systems (V2X) to support safety, mobility and environmental applications using vehicle Dedicated Short Range Communications (DSRC)\Wireless Access for Vehicular Environments (WAVE).  This program has support from most of the automakers and a number of state departments of transportation.

Congestion Pricing

*UPDATED* Also “Variable Pricing.” Toll facility pricing that is set based on traffic demand, with higher toll rates at high-traffic periods and lower toll rates at low-traffic periods. Rates may vary by time of day, day of the week, or may vary dynamically based on current traffic conditions. Value Pricing is designed to achieve performance objectives to reduce traffic congestion and delay by shifting travel to less congested periods or different modes, encouraging high vehicle occupancy, or reducing the number of vehicular trips taken.

Concessionaire Company

Mainly in Europe: A company which is awarded, by a concessioning Administration, the operation of a toll facility. Usually the contract includes the design, construction, financing and operation of the facility.


*UPDATED* Toll concessions are contracts to develop and/or operate toll facilities on behalf of a facility owner - normally a public sector entity. Toll concession contracts are long-term agreements, often for 30 years or more. Service Area concessions are contracts to develop and/or operate driver service areas and gas stations.

Closed Toll Section

Closed System

*UPDATED* An arrangement of toll points on a facility to ensure that all vehicles pay some toll amount for use of the facility.

Closed Entry-Exit System

*NEW* A toll concept employing toll points (either plazas or toll zones) at every facility entrance and exit to detect trip length for toll rate setting and to not allow any free movements.

Closed Barrier System

*UPDATED* An arrangement of mainline and ramp toll plazas and/or toll zones with discrete toll schedules, located such that every possible trip incurs at least one toll. A closed barrier system may use ORT Toll Zones, or toll plazas.

Clearinghouse (Toll Authorities)

Provides all requisite financial services to transfer monies between participating Authorities; provides accurate and timely downloads of customer accounts, violations and all other information necessary for an interoperable system.

Clearinghouse (Financial)

A Clearinghouse Network routes transactions for reconciliation. The term applies to all types of financial transactions, not just toll transactions. Examples of Clearinghouses (or Clearinghouse Networks) include the Federal Reserve Automated Clearinghouse Network (ACH), VISA, MasterCard, American Express, Pulse & Cirrus. It is important to note the distinction between a Clearinghouse and a Fiduciary (defined below): A Fiduciary converts transactions into Funds, a Clearinghouse routes transactions to Fiduciaries.


To determine the category of the vehicle to be tolled based upon its specific structure, weight, axles, tires, etc.


Common EFC System for an ASECAP Road tolling European system. CESARE is a project set up by ASECAP and partially funded by the European Union with the intention of specifying, designing, developing, promoting and implementing a common interoperable Electronic Fee Collection System (EFC) on European toll roads.

Certificate Authority

A Certificate Authority (CA) is an organization that issues and manages security credentials and Keys for message encryption and decryption. As part of Public Key Infrastructure (PKI), the CA provides certificates (Keys) to Issuers. The Keys are used to encrypt, sign and secure Electronic Payment Services (EPS) transactions.

Closed Circuit Television

Cashless Tolling
