Traffic TechnologySkyToll has begun to build portals for new electronic toll system in Croatia
The erection of the first seven portals on the A3 motorway on November 4, 2025, marked the start of another key phase of the project in Croatia. The project includes laying foundations, assembling the steel structure itself, replacing or installing new guardrails, carrying out electrical installations, and other related works. Construction activities will take place in multiple phases, during which traffic will be administered by temporary traffic measures. The works are planned for periods of lower traffic intensity, mainly in the evening and night hours.
- The current phase of Crolibertas system implementation is a technically and infrastructurally demanding project, which includes:
- The installation of a total of 212 portals throughout the motorway network in Croatia;
- The assembly of advanced IT equipment;
- Construction works on sections in the course of their regular operation;
- The establishment of backoffice data processing centres.
Simultaneously with the installation of portals and the installation of technology (cameras and antennas), tests of the functionality of individual parts of the system will be carried out as well. After all installations are completed and connectivity is commissioned, comprehensive system testing will follow at the network level.
The collection will be fully electronic, without the need to stop vehicles at the beginning or the end of a toll section. From a technical point of view, the system will be based on two key technologies:
- ALPR (Automatic Licence Plate Recognition), which recognises the licence plate numbers of passing vehicles in real time, is used for collecting tolls from occasional light vehicle users and for monitoring toll payments for all vehicles
- DSRC (Dedicated Short Range Communication) for collecting tolls from ENC device users – i.e. frequent motorway users passenger cars and all lorries, which are required to have an ENC unit.
The bid by the consortium of SkyToll and TollNet, both part of the ITIS Holding group, was selected as the most favourable one in a competition of ten bidders. The new toll collection system will be introduced on all Croatian motorways administered by Hrvatske Autoceste, Bina Istra and Autocesta Zagreb-Macelj.
