Abstract: Aiming at the problem of lighting energy waste caused by low traffic flow of secondary and tertiary high? way tunnels in West Sichuan Plateau, a real vehicle running test is conducted by using TOBIIGLASESS2 eye tracker.Through direct calculation, the stopping sight distances of the drivers in the middle section of the plateau tunnels with low traffic volume under different lighting conditions are obtained, and comparison with the minimum stopping sight distance as required in Guidelines for Design of Lighting of Highway Tunnels (2014 Editoin) is made. Under the premise of ensuring the traffic safety of drivers, it is recommended that the lighting brightness design standard for the middle section of this kind of tunnels should be 0.5 cd/m2. Using Dialux software, the numerical simulation is conducted for the lighting conditions in the middle section of secondary and tertiary highway tunnels with low traffic volume on the Western Sichuan Plateau, and the engineering economy under different lighting conditions is analyzed. It is recommended that the lamps in the Balangshan tunnel should be arranged in the middle position with an unequal interval of 30 m.
