LARGE SCALE EXPERIMENT OF CONTOUR MARKING FOR TRUCKS

During the last 10 years several large scale experiments were made on behalf of introducing a contour marking for trucks for better conspicuity. The results comparing the accident rates of marked and unmarked trucks always showed a reduction of the number of accidents. This was the reason for preparing a new ECE-Draft Regulation: Uniform provisions concerning the approval to retroreflective marking of heavy and long vehicles and their trailers as an annex to the agreement: Concerning the adoption of uniform conditions of approval and reciprocal recognition of approval for motor vehicle equipment and parts. Within this Draft Regulation several requirements were made on behalf of (1) geometrical dimensions; (2) coefficients of retroreflection; (3) chromaticity co-ordinates and others. In a large scale experiment restricted to Germany it was allowed by only special permission to equip trucks and trailers with logos, graphics, letters, and characters of different material types and colours. The geometrical data and the coefficients of retroreflection of the marking of trucks and trailers were measured during the procedure of giving the special permission for installation of the markings.
