The influence of road marking visibility on lateral vehicle position and driving speed

Road markings are a vital element of horizontal signalling, forming an integral part of traffic signalling. Their role in traffic safety involves providing timely warnings, safe guidance, and necessary information to ensure the safe movement of all road users. Under conditions of reduced visibility, often due to weather (night, fog, rain, etc.), road markings are often the only guide for drivers to determine the direction of the road. Research conducted using a driving simulator demonstrated the influence of road markings on driver behaviour, specifically on lateral vehicle position and driving speed. The results indicated that drivers behave differently depending on the visibility of road markings. A total of 31 participants took part in the study, with data collected on driving speed and lateral vehicle position for three different visibility levels of road markings on a straight road and on a right and left curve.
