The lighting glare of high-speed train driving environment has an important influence on the interface design. How to validly evaluate the glare at the design stage is currently a hard problem in the design of high speed train driving interface. Considering the complexity of lighting environment of high-speed train driving interface, the difficulties to determine the shapes and boundaries of the glare sources, and the difficulties to accurately acquire the calculate parameters for the glare calculation, this paper proposes a lighting glare evaluation model for high-speed train driving interface based on the unified glare rating(UGR) evaluation formula and small light sources UGR correction formula. Files, which including the driver’s visual simulation image file and the image pixels photometry information file, are acquired by visual simulation method. The parameter values for the glare evaluation model are obtained by identifying, integrating, and filtering the glare source pixels in the visual simulation image. Subsequently, the parameter values can be used as the input values to evaluate the lighting glare of high-speed train driving interface. 12 lighting schemes of the CRH3 driving interface are designed and evaluated by subjective evaluation experiments and the proposed lighting glare evaluation method. The results show that the evaluation value of the proposed method has a significant linear relationship with the subjective sensation. The proposed method can validly evaluate the lighting glare of high-speed train driving interface at the design stage. The method can provide guidance for the design and optimization of high-speed train driving interface.
