Claim 14:
15. A method of computing instructions for painting road markings detectable in infrared spectral range, comprising:
using at least one processor for:
computing instructions for painting road markings expressed using alternating high and low infrared reflective tiles on a road surface using at least one paint material characterized by: (1) reflecting light in visible light spectral range deviating less than a first value from the light reflected by the road surface, and (2) reflecting light in an infrared spectral range deviating more than a second value from the light reflected by the road surface; and
outputting the painting instructions for applying the at least one paint material on the road the road such that the road markings are visible in the infrared spectral range and imperceptible in the visible spectral range.
