Free-flow Tolling System

Free-flow Tolling System (FFTS) is a technology-based solution to enable the collection of tunnel tolls without requiring a vehicle to stop at a toll booth, avoiding disruption to traffic flow arising from the need to stop at toll booths for manual toll payment. 

Autotoll obtained a government contract for “Tseung Kwan O – Lam Tin Tunnel – Trial Installation and Evaluation of Free-Flow Tolling System” in 2017, it comprised the design, supply, installation, data collection, analysis of test results and reporting in relation to the trial of a Free-Flow Tolling System integrating the technologies of Radio Frequency Identification (RFID), Automatic Number Plate Recognition (ANPR), On-Board Unit (OBU), and/or other advanced technologies.

And obtained another government contract for “Free-flow Tolling System in Hong Kong – Development of Backend System” in 2021, it comprised the design, supply, delivery, installation, testing and commissioning for the Backend System serving the Free-flow Tolling System at government tolled roads/tunnels and other related services, and the Backend System expansion works.

Now, Autotoll’s turnkey solution can adopt both Radio Frequency Identification which requires affixing an RFID tag to the vehicle, i.e., the installation of in-vehicle units, and Automatic Number Plate Recognition. By using FFTS, a vehicle will be detected by the field equipment of FFTS by:

  • reading an IVU affixed to a vehicle; or
  • through recognition of the vehicle registration mark on a vehicle number plate through ANPR.

Autotoll offers professional turnkey solution in design, supply, installation, testing, commissioning and training lessons to customers.
