Influence of Headlight Contamination on the Stopping Distance and Maximum Allowable Speed on Roads Covered with Chemical Anti-Icing Materials

Abstract

The article aims to identify the influence of headlight contamination on the stopping distance and allowable speed on roads covered with chemical anti-icing materials at night. Headlight contamination effects were analyzed for determining the maximum allowable vehicle speed on winter roads covered with chemical anti-icing materials in dark conditions. The maximum allowable speed and stopping distance of the vehicle with contaminated headlights were calculated accounting for road visibility in dark conditions. New data on the influence of car headlight contamination, length of its stopping distance and maximum allowable speed on roads covered with chemical anti-icing materials were obtained.
