The project included the following:

• preparation of project documentation for the zoning approval of data connections
• documentation for the zoning approval and building approval for low voltage connections
• documentation for the building approval for portal technology
• documentation for the building approval and implementation project documentation for portal constructions and construction modifications

In the first phase, 170 toll gates were constructed. Road signalling portals were used for technology installation around the Valík tunnel on D5 highway. The total length of paid highways and express ways is 970 kilometers.
Individual highways and speedways have the number of toll gates: D1-38, D2-6, D3-1, D5-23, D89-13, D11-11, R1-7, R4-7, R6-8, R7-5, R10-15, R35-13, R46-12, R48-1, R52-4, R55-1, R56-5, R63-2.
Gate Types
The gates are divided according to their function into registration gates (tolling) to record vehicles passing through them by means of an onboard unit placed on the front windscreen of the truck, and into check gates that not only register vehicles but also identify them (recognition of licence plate, number of axles) and compare with a central database.
Description of toll collection method during travel on paid sections
After a vehicle enter the communication area, its onboard unit responses to periodically broadcasted Transceiver Service Table (BST) using its own Vehicle Service Table (VST) that is transmitted to the toll station facility of the provider. Based on the information received from the tolling point, the height of the toll is calculated under consideration to the vehicle category, tolling section and time of passage. Tariff information is stored in the tariff table of the transceiver control unit. In case the vehicle is equipped with a pre-paid onboard unit the balance account stored in the onboard unit is decreased. For each pre-paid contract a special shadow account is maintained that is checked against the balance on the onboard unit. In case the vehicle is equipped with a post-paid onboard unit the amount charged is written into the unit and billed to the corresponding user of the road.
