Aiming at the contradiction between lighting safety and energy saving in highway tunnels

especially in mountainous expressway tunnels with less traffic volume

this paper proposes an intelligent lighting control system for tunnels

which integrates traffic volume

brightness outside the tunnel and color temperature control. Firstly

the basic parameters of the tunnel are collected

and then the reduction coefficient of the tunnel entrance section

the brightness of the tunnel reinforcement section and the brightness of the tunnel basic section are determined according to the real-time traffic volume and the brightness outside the tunnel. At the same time

the color temperature control technology is used to adjust the color temperature of lamps in the tunnel

so as to create a harmonious tunnel lighting environment for drivers. The research and application of tunnel intelligent lighting control system can not only ensure the safety of tunnel lighting

but also further reduce the energy consumption of tunnel lighting

and realize the intelligent energy-saving lighting control according to the real-time dynamic traffic volume. The system plays a positive role in improving the safety and energy saving level of tunnel lighting

promoting the upgrading of tunnel quality and the green and low-carbon level of highway traffic.
