Reviewer 3 Report Tunnel lighting design is critical in traffic safety. In this manuscript, the authors proposed a tunnel lighting design based on the usage of daylight . Compare with traditional electrical lighting , their lighting design shows increased average luminance, luminance uniformity, and reduced energy consumption.
Typically, tunnel on-demand lighting refers to accurate estimations of the demand for luminance in the tunnel based on the actual traffic flow in the highway tunnel and change in luminance outside the tunnel , followed by dynamic dimming control.

On the other hand, the greater artificial lighting luminance is bound to result in high energy consumption. Therefore, developing energy-efficient lighting for the entrance section of tunnels is crucial to ensure traffic safety. Currently, attempts to improve tunnel entrance lighting can be roughly divided into two categories.
The solutions traditionally implemented, based on light-pipes hanging from the vault, seemed reasonable because the leakages of light-pipes can emit luminous flux like projectors, but had the disadvantage of needing higher clearance gauges with the consequent costs in drilling, building materials, works and maintenance.
