SAFER NIGHT DRIVING DUE TO THE USE OF ROAD BOUNDARY REFLECTORS

SAEKRARE MOERKERTRAFIK MED VAEGKANTREFLEKTORER

Improved visual guidance along highways is increasingly essential since centre line markings and car headlights become dirty much more rapidly due to greater use of studded tyres and salt on the roads. Provision of reflectors along road boundaries is one solution. Tests were carried out using 13 different types of reflector-post construction. Reflectors must be washed 5-8 times during the dark part of the year in order to maintain good reflectivity. Only one type, where the reflector is placed inside a horizontal pipe, required no washing. This type has been installed along 26 km of unlit roads in the Gothenburg area. /TRRL/
