PROBLEM TO BE SOLVED: To provide a tunnel light control system which allows for adjustment of the output of lighting in tunnel to a set value, based on easy and correct road surface luminance measurement in the tunnel.SOLUTION: A tunnel light control system (1A, 1B, 1C, 1D) includes a lighting system (2) arranged in a tunnel, a vehicle side device (3) having a road surface luminance measurement device (30) for measuring the road surface luminance in a tunnel by using a sensor (30a) mounted on a vehicle (V), and a control section (25, 35, 45) generating the luminance correction information for performing the lighting control of the lighting system (2) based on the road surface luminance measured by the road surface luminance measurement device (30). |
