 Road tunnels and technology in an operational perspective

Intelligent lighting solutions for tunnels Featured

Written by  Nov 07, 2017

Tunnel operators face the challenge of illuminating the tunnels evenly according to given specifications and controlling the intensity depending on the situation. Its now available systems that enables operators to visualise system status and the condition of the light, in addition be more energy efficient and save costs. 

The Tunnel Lighting Addressable Control System (TLACS) system is an example of such system and this can monitor and control lights from a control centre, by interfacing the SCADA system, where the lamps can be turned on or off, on-demand manually, automatically upon receiving a signal from the luminance camera, or according to a predetermined schedule. The TLACS enables operators to remotely configure and manage the tunnel’s lighting system, enabling it to visualise system status and the condition on the light.

Suppliers have developed lighting solutions with state-of-the-art LED technology. In such solutions, the LED lights are controlled directly, or via so-called Driver Boxes. In the boxes, the LED drivers for adjusting the lamps are installed. The exact position of the lamps and Driver Boxes are defined on the basis of a photometric analysis of the tunnel lighting. In parallel with the clarification work, power and bus cables can be delivered directly to the site, configured and ready for use. Time-consuming management of the wiring and subsequent switching is not necessary.

This technology can ensure that the tunnel operator's specifications or statutory regulations are fully met. In addition, only as much light is generated as it is needed at all times, which is positive in terms of energy costs.
