Pavement marking maintenance refers to the process of ensuring that pavement markings are clear, visible, and in good condition to enhance road safety and traffic flow. Pavement markings are essential for guiding drivers, cyclists, and pedestrians, and they help delineate travel lanes and indicate traffic rules. Regular maintenance includes checking for wear, fading, or missing sections, which can reduce visibility and safety. Proper maintenance can significantly reduce accidents, with studies showing that clear markings can lower crash rates by up to 25%. Overall, maintaining pavement markings is crucial for ensuring safe and efficient traffic flow on roads.
