Characterizing Luminous Efficiency Functions for a Simulated Mesopic Night Driving Task Based on Reaction Time

This study aimed to test the luminous efficiency functions V(λ), V'(λ), V-sub-1-sub-0(λ) and their linear combinations on the basis of a data set acquired from a simulated mesopic night-time driving experiment, and to provide 'real-world' data for the 'X framework' or 'linear combination model' and find its limits in a practical situation. Human performance was measured by reaction time. Results show that the single parameter of the linear combination of photopic and scotopic luminous efficiency functions can be determined analytically with little variation for a given mesopic background luminance level and a given visual target color, but the computation leads to considerable deviations comparing all 3 target colors (red, green, and blue) used in the experiment. It was concluded that, for the given experimental conditions, the single parameter of the linear combination model has increasing deviation for lower background luminance levels.
