Abstract: The disclosure relates to a method for measuring parameters of roadway low-position lighting fixtures, comprising: selecting a plurality of sets of low-position lighting fixtures with preset color temperatures and color rendering indexes, or a set of low-position lighting fixtures configurable with multiple pairs of preset color temperature and color rendering index; for each set of the plurality of sets of low-position lighting fixtures or each pair of preset color temperature and color rendering index in the set of low-position lighting fixtures, dynamically recognizing a target under different predetermined luminance levels at different predetermined operating speeds; using obtained samples to fit a relationship model between recognition distance and luminance; and based on the fitted relationship model, determining at least one set of said plurality of sets of low-position lighting fixtures or determining at least one pair of preset color temperature and color rendering index for said set of low-position lighting fixtures. The disclosure also relates to an installation method of roadway low-position lighting fixtures and a road on which the lighting fixtures are installed. The invention overcomes the problems in the existing lighting fixture design in terms of the characteristic indicators of light source, installation height and light distribution.
