The visibility of the road by night conditions depends on the used headlights and is influencing together with the other conditions (curves, velocity of the car, etc.) on the traffic security. Measurement results of the lighting-up of the road by headlights of the type H4 with low beam are presented as well as the photometric requirements for unsymetrical lights regulated by EEC. The eximation path was 50 m long and the measurement points were on both sides of the road; 3 on the left side and 5 on the right side always measured in 3 levels: on the road, 0,6 and 1,2 m high. The results were analyzed and presented in the tables. The influence of the road curve radius is given. The analysis of the results shows that the safety car velocity is 50 to 70 km/h. Proposals for the improvement of traffic safety through regulations, technical and legislative are presented. (Jarc)
