Based on optimized tunnel luminaire installation parameters, a simulation experiment of tunnel lighting and a tunnel model lighting experiment were carried out to study the energy-saving of tunnel lighting with low cost. Yanlieshan highway tunnel was selected as object. Based on the tunnel structure sizes (TSS) and selected LED luminaires, the optimized stagger luminaire installation parameters (OSLIPs) were obtained by the lighting parameters optimization model (LPOM) on stagger luminaire distribution (SLD) from reference. Simulation experiment of tunnel lighting was accomplished with DIALux based on the TSS and OSLIPs. A similar tunnel model was designed and built according to the TSS and similarity theory, a lighting experiment was accomplished with the similar tunnel model, the road-surface-illuminance (RSI) data were obtained and reversely treated, and compared with the simulation experiment results. The horizontal RSI of the two ways coincides well, which proves the correctness of the LPOM, the feasibility of the lighting experimental study with tunnel model and validity of the experiment method.
