Glossary of Terms

IBTTA’s transportation Glossary of Terms is an ever-changing list of terms used within the transportation and tolling industry. The Glossary was updated in August 2018.  If you have suggestions for future additions, please contact us.


  Glossary of Terms

The Council of Platinum Sponsors (CoPS) TollMiner & Glossary Working Group was created to improve definitions of toll facility concepts that are used in the IBTTA TollMiner Data Visualization tool. Since the TollMiner data and structure are closely linked to the IBTTA Glossary, a review and draft update of the glossary was performed during 2021.

Local Area Network

Lane Controller

A specific type of in-lane (generally, but not always) equipment used to respond to or detect in-lane sensors (AVI Reader, treadles, beam detectors, loops, etc.) and using precision algorithms, make appropriate decisions (raise gate, take violation image, activate driver feedback lights, etc.).


Transactions where no revenue is collected, or revenue is not fully collected. (Does not include non-revenue or violation transactions wherein the vehicle is either not permitted to cross the barrier or where a violation image is taken.)


Commercial brand of the common interoperable Electronic Fee Collection (EFC) used for light vehicles in the French concession context.

Loop Detector

A vehicle sensor used either to count or detect the presence of a vehicle in the toll lane. The metallic mass of a vehicle located above wires laid in the concrete produce electromagnetic signals that can be sensed electronically.


Leistungsabhängige Schwerverkehrsabgabe - The LSVA (Leistungsabhängige Schwerverkehrsabgabe) is a nationwide distance-related road fee that replaced an annual flat fee imposed on heavy vehicles in Switzerland.  The LSVA legislation resulted from treaties with the European Union when weight limits on transport vehicles carrying goods across the Alps were increased from 28 tons to 40 tons.  Studies forecast that this weight limit increase would double heavy goods traffic on the Swiss road network by 2015 unless the LSVA were enacted.  The intent of the measure was to encourage rail transport rather than road transport.
