Patent ID: 7980782

Claim:
A traffic safety integrated system for a site of a road, railway, airport, or harbor having low visibility conditions, comprising: one or more of road markings provided on a traffic area of said site; at least one light-emitting device for generating at least one light beam, the light-emitting device being disposed at a distance from the traffic area and comprising, a housing, a semiconductor source comprising a laser source or a LED generating the at least one light beam, and a projector projecting the at least one light beam toward the one or more road markings, the semiconductor source and the projector being disposed within the housing; a support structure securing said light-emitting device in a predetermined stationary position with respect to said site; and means for controlling said at least one light-emitting device for generating said at least one beam, wherein said beam generates an image corresponding to said one or more road markings that is visible to drivers driving over said traffic area in a predetermined drive direction, and not to drivers driving in an opposite direction, wherein said means for controlling comprise at least one microprocessor control unit for controlling said at least one projector or said semiconductor source, and wherein said microprocessor control unit comprises adjustment means, for adjusting a distance of a diffractive lens to said semiconductor source, such to change size of said at least one light beam or of said projected images, thereby alerting the drivers about the one or more road markings and increasing traffic safety.
