Understanding Tunnel Lighting: Ensuring Safety and Visibility on the Road
Tunnels are vital infrastructure elements that connect cities, reduce travel times, and improve connectivity. However, navigating through tunnels can pose challenges for drivers due to changes in lighting conditions. This is why proper tunnel lighting design is essential for maintaining safety and visibility.
At SIGNA SYSTEMS, we combine expertise, innovation, and technology to provide tunnel lighting systems that prioritize driver safety, energy efficiency, and sustainability. Our designs are guided by internationally accepted standards, such as CIE 88:2004, ensuring that every project meets the highest performance requirements.
Why Tunnel Lighting Matters:
The goal of tunnel lighting is to accommodate the human eye’s adaptation from bright to dark conditions (or vice versa) as a driver enters or exits a tunnel. Inadequate or poorly designed lighting can lead to visual discomfort, reduced reaction times, and safety hazards.
Tunnel lighting consists of five key zones, each serving different purposes:
- Access Zone – Prepares drivers for the transition from daylight to tunnel conditions.
- Threshold Zone – Ensures brightness levels align with external light conditions.
- Transition Zone – Gradually reduces luminance levels as vehicles move into the interior zone.
- Interior Zone – Maintains consistent visibility throughout the tunnel.
- Exit Zone – Allows eyes to adapt from dark conditions back to brighter exterior light.
At SIGNA SYSTEMS, our systems are designed to ensure that these zones are illuminated optimally, helping drivers maintain visibility while reducing the risk of glare or temporary blindness.
