Road lighting has one very clear objective, to provide visual conditions for all road users, who have to be able to identify and judge the course of the road, the state and boundaries of the carriageway and hazards that may be present at any time. An efficient lighting should be economical in the sense of maintenance and also energy consumption besides having top performance in any condition, whether in late night or early in the morning, in wet or dry conditions. To achieve that, many aspects should be taken into consideration in the designing, commissioning and installing process. Environmental issues such as minimized glare and other light pollution area among a few of them. For example, the complexity of road tunnel lighting design focuses upon 4 specific sections, which is Threshold, Transition, Interior and Exit. To enable drivers to proceed through a tunnel safely, without slowing down, the luminance levels throughout the zones must be reduced gradually to allow drivers vision to adapt from the lighting conditions outside the tunnel to those of the Interior. Adaptation is assisted by ensuring high wall brightness and for maximum safety.
