Abstract

This paper endeavors to analyze road lighting quality with the influence of luminous coefficients of the tunnel wall, with lighting design software DIALUX which simulates tunnel lighting, by improving the reflection coefficient of the tunnel wall materials. The result of Analysis shows that high-tunnel side wall reflection coefficient not only helps to improve the tunnel intensity of illumination, but also improves the luminance of the tunnel; under certain circumstances of the road surface luminance, high reflective coefficient of the tunnel walls is helpful to tunnel lighting energy consumption reduction.
