With the rapid development of highway construction, highway tunnels, as an important part of it, play a crucial role in traffic safety with their tunnel lighting brightness, while also needing to address energy consumption issues. This paper analyzes existing technical research, proposes a control strategy based on traffic volume adjustment, and further optimizes the brightness of highway tunnel lighting. By establishing a segmented model for tunnel lighting, the entrance segment brightness attenuation coefficient K related to traffic volume and vehicle speed is fitted using MATLAB to obtain the equation for optimizing tunnel lighting brightness. Based on the control strategy of traffic volume adjustment, the system achieves lighting when vehicles approach and dimming when they depart. Simulation experiment results demonstrate that under the control strategy based on traffic volume adjustment, the system can ensure driving safety and effectively reduce energy consumption. This strategy, particularly for the application of long tunnels with low traffic volume, is of significant importance.
