Visual spectrum means light with a wavelength within the range of the perceptual limits of the human eyes: 380-780 nm. 2/ A system for indirect vision is intended to detect relevant road users. The relevancy of a road user is defined by his or her position and (potential) speed. More or less in proportion with the speed of the pedestrian-cyclist- moped driver, the dimensions of these road users increase as well. For detection purposes a moped driver (D = 0.8 m) at 40 m distance would be equal to a pedestrian (D = 0.5 m) at a distance of 25 m. Considering the speeds, the moped driver would be selected as the criterion for the detection size; for that reason an object with a size of 0.8 m shall be used for determining the detection performance.
