Abstract：This paper takes road tunnel luminous coatings for the study , conducts research on numerical simulation model , in order to establish a road tunnel simulation model of luminous coatings which takes the average luminance of road surface as key evaluation .Use three-dimensional numerical simulation methodto research the effect of different laying ranges of luminous coatings which start growing with 3m height on both sides of tunnel walls, and simulate seven cases that including laying range of none , 2m, 3m, 4.54m, 5.71m, 6.5m, 7m and all section .By summarizing and analyzing the key parameters such as average luminance of road surface and value of energy efficiency , a result can be calculated that the variation of average luminance of road surface in tunnel range from 8.7cd/m2 to 12.1cd/m2 , value of energy efficiency decreases with increasing range of laying , and the economical efficiency is highest in the condition of laying range 3m.
