An integrated system for traffic safety (1), particularly in low visibility conditions, for use on a site (2) of a road, railway, airport, harbor or the like, which comprises road markings and/or signs (3). The system (1) comprises at least one light-emitting device (4) for generating at least one light beam (5). One feature of the invention is that it comprises means (6) for controlling the light-emitting device (4) to generate the beam (5). The device has such a predetermined relative position with respect to said site (2) as to selectively interact with the road markings and/or signs (3) and to make the beam (5) only visible to the drivers that drive over the site (2) in a predetermined drive direction, and not to those who drive in the opposite direction. An integrated method for traffic safety, in conditions and sites as described above, including the steps of providing road markings and/or signs (3) on a road site (2) (step a), providing at least one light-emitting device (4) for emitting at least one light beam (5) (step b), emitting the beam (5) (step c) and conforming and orienting it toward the site (2) to selectively hit the road markings and/or signs (3) thereon (step d).

The invention claimed is: 1. 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, anda 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; andmeans 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, andwherein 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.
