| Abstract: | The length and brightness of tunnel entrance are closely related to traffic safety.According to the CIE88 theory,this paper deduces the calculation formula of length and brightness of shading sheds at tunnel entrance based on traffic safety,which provides a theoretical basis for the design of shading sheds.The case study shows that the application of shading sheds can effectively reduce the project cost.Compared with traditional lighting,it not only has the effect of energy saving and emission reduction,but also has better economic advantages. |
