英文摘要

      To solve the problem of excessive changes in the road surface luminance under different visibility levels and the consequent traffic safety and energy wastage, a dynamic optimization and intelligent control method that can improve the lighting environment of highway tunnel is proposed in this paper. Firstly, through field tests and data analysis of highway tunnels under different space-time conditions, the variation of visibility in tunnels is obtained. Secondly, the influence of visibility on the lighting environment is considered on the basis of the traditional lighting design of highway tunnels. And an on-demand lighting and dynamic optimization model based on visibility, traffic volume, vehicle speed, road surface luminance and lighting luminance is established. Subsequently, the measured data of highway tunnels in different regions are used as samples. Combining the typical lighting scenes of highway tunnels and fuzzy radial basis neural network algorithm to build a highway tunnel lighting intelligent control model. Finally, the effectiveness of the model is shown by simulation experiments. The results show that the proposed optimal control method can take into account energy saving on the premise of ensuring the safety of tunnel lighting.
