Aims of tunnel lighting


Driver comfort

Tunnel lighting should create the correct visual environment for the road user irrespective of the external ambient conditions.


Road safety

The safety of road tunnel users is paramount; traffic needs to enter, pass through and exit the tunnel without any adverse effects to driving characteristics.


Cost saving

With growing concerns over the increasing cost and environmental impact of high energy consumption tunnel lighting that uses less power and produces fewer carbon emissions is essential.


Reduced maintenance

Tunnel lighting should have the longest lifetime possible, minimising the need for tunnel closures and major disruption, thereby reducing maintenance costs considerably.
