Abstract：In order to establish a multi-scene visual preference evaluation model within the passenger compartment of high-speed train,this paper took the passenger compartment of a new type of high-speed train set prototype as the research carrier,and set up three types of typical scenes:daytime ride,nighttime ride and nighttime rest,and used 4 correlated color temperatures(CCT)(3000 K,3800 K,4500 K and 5300 K)and 5 illuminances(79 lx,126 lx,199 lx,315 lx and 500 lx)to construct 20 groups of light environment conditions in combination,and the subjective preference evaluation data of 27 subjects were collected.Fuzzy analytic hierarchy process(FAHP)was used to determine the three-dimensional weights of light environment preference(34.67％),color rendering preference(26.66％)and visual perception(38.67％),and a multi-scene evaluation model was constructed by combining nonlinear surface fitting:P=z0+aE+bT+cE2+dT2+fET,in which P is the visual preference score,E is the sitting/recumbent eye illuminance of the passenger,T is the sitting/recumbent eye CCT,and the differences in evaluation models for different scenes are mainly the differences in model coefficients z0,a,b,c,d,and f.The study breaks through the limitation of single-parameter analysis,reveals the synergistic mechanism of CCT-illuminance in multiple scenes,and provides certain theoretical basis and support for the design of passenger indoor lighting environment in high-speed trains.
