Tunnel Brančići

The Tunnel Brančići project was carried out from June 2018 to May 2019 on Highway E763 – Section V, part Lajkovac – Ljig, under investor Javno preduzeće (Public Enterprise) – Putevi Srbije and Energoprojekt Niskogradnja Beograd. It included performance of the electrical works and traffic signalization within the tunnel.

Traffic signalization is divided into variable and permanent signalization.

Variable traffic signalization is performed by traffic signs with variable content. Variable traffic signs are placed in the tunnel, on the approaches to the “Ljig” loop and on the parking access.

In the loop zone, PTZ cameras with predefined focus zones are placed on the portals, which rotate in time on the graphical user interface of the control and operational center.

PTZ cameras are also installed in the parking and resort area. An ALPR camera is installed at all entrances to the resort to detect license plates, as part of the system for the detection of oversized vehicles (transport of hazardous materials).

Variable traffic signals are divided according to the type of signs into:

• Variable traffic signs in front of the tunnel
• Variable traffic signs in the tunnel

Traffic lights are provided at the entrance and exit of the tunnel for the purpose of traffic regulation, as well as closer portals at the entrances to the left and right tunnel pipe. Variable traffic signalization is controlled via automation cabinets, located in the immediate vicinity of signs that are controlled in SOS niches as well as in automation cabinets in the tunnel zone at the entrance or exit from the tunnel.

In addition to the great economic impact on this part of Serbia, the section of the highway E-763 Belgrade – Požega, represents a step of the Trans-European Highway (TEM) which in Serbia connects the basic direction of the TEM with the Adriatic Sea. Within the primary network of Serbia, this road route should take over long-distance flows from the existing main roads M-21 (Novi Sad – Valjevo – Užice – Bijelo Polje), M-22 (in the part Belgrade – Čačak) and further, on the territory of Montenegro, from the road M-2 (in the part Bijelo Polje – Podgorica – Adriatic Sea). On the stretch Preljina – Požega (in length of approx. 34.2 km) the corridor coincides with the corridor of the “West Moravian Highway” E-761, Pojate – Kruševac – Kraljevo – Preljina – Požega.
