An apparatus for improving safety in land vehicle traffic. This invention is a road scanning apparatus fitted to the front corners of a road vehicle which can continuously warn the driver of vehicle proximity to the painted traffic lane marks on the normal road surface. The scanning system detects the change in intensity of retro-reflected light from asphalt to a painted line mark as well as geometric characteristics of the line. Modification to existing roads is thus uneccessary. Moreover, this apparatus can be enhanced to include additional capabilities such as a optical communication system whereby coded information, e.g. 'Bar Codes' painted onto road surfaces can be read and decoded and transmitted to the vehicle's occupants This information can also be recorded for later use. Other such coded information will allow for automatic control of vehicles from data scanned continuously while driving.
