[0002] With the rapid development of the national transportation, there are more and more tunnels in highway and expressway traffic. In the operation and management of highway tunnels after completion, the lighting electricity cost is a major component. In some sparsely populated areas with few vehicles or with fluctuating traffic volumes, that is, the tunnels in these areas are mostly in a vehicle-free state for most of the time.
