The difference between luminance in design versus road surface in the lighting environment
of long tunnels often results in the road surface luminance not reaching safety standards. To …

Tunnel shading shed instead of tunnel lighting is one of the ideal ways to reduce the
tremendous energy consumption at the entrance (section 2.1), but at present the length of …

In order to achieve the goal of energy-saving and safety driving in tunnel, this paper
proposes an energy-saving fuzzy control system for highway tunnel lighting. Firstly, a control …

In order to meet the requirements of traffic safety and energy-saving in tunnel, a “vehicle in,
light brightens; vehicle out, light darkens” energy-saving control system is proposed. The …

The freeway tunnel accidents in China over the last decade have attracted more attention on
the operation safety in freeway tunnels. To explore the safety of the traffic driving …

This paper presents an intelligent control method for tunnel lighting based on traffic volume.
The monitoring data for a period of 12 days of the Chibai tunnel (located in the Jilin province …

Tunnel lighting constitutes one of the major expenses incurred in transportation lighting, and
hence substantial research has been conducted to improve the efficiency of lighting and …

This study describes applying the visual target color and spectra of light sources to calculate
the perceived luminance in a tunnel interior lighting environment. The proposed approach …
