N2  - Lothian Region's Transportation Committee instructed their Department of Highways to investigate the possibility of installing a system to reduce the incidence of overheight vehicles colliding with bridges at two sites. Despite the demanding requirements, a company was discovered with the necessary optical, electronic and mechanical expertise to construct and install the equipment. The system is based on the use of two solid-state light sources transmitting invisible beams of infrared light from a pole on one side of the road to two detectors mounted on a pole on the opposite side of the road. When the system detects the passage of an overheight vehicle, it promptly activates a fiber-optic vehicle diversion sign.     <p>Language: en</p>
