Abstract：Based on visual characteristic of short tunnel driving , the effect of intervisibility for visual adaptation is analyzed .Combined with luminance evolution along the tunnel in Guide for the Lighting of Road Tunnels and Underpasses proposed by CIE , the reasonability of design method for short tunnel is illustrated, which is proposed by Guidelines for Design of Lighting of Highway Tunnel.By lighting optimization design for a specific short tunnel with Guidelines, the energy consumption of each lighting zone can be reduced at different levels compared with that deduced by Speifications.And for general short tunnel, the total energy-saving can reach to 60%compared to earlier Speifications.
