Claim 8:
9. A method of painting enhanced driving assistance markings visible in infrared light spectrum, comprising:
using at least one processor for:
generating enhanced driving assistance markings expressing driving information relating to at least one road segment;
computing instructions for painting a surface of at least one element of the at least one road segment using at least one paint material characterized by (1) reflecting light in a visible light spectral range deviating less than a first value from the visible light spectral range reflected by the surface and (2) transferring more than a second value of light in at least one infrared spectral range such that the enhanced driving assistance markings presented under the at least one paint material are visible in the at least one infrared spectral range; and
outputting the painting instructions for applying the at least one paint material on the surface.
