linemarking

Linemarking refers to the application of painted lines, symbols, and words on road surfaces and in parking areas to guide traffic, regulate speeds, indicate lanes and turns, and mark parking bays or pedestrian crossings. It includes center and edge lines, lane division, arrows, crosswalks, stop lines, and bicycle facilities, as well as special markings for school zones or reserved spaces.

Application relies on specialized equipment and a range of materials, including thermoplastic, cold-applied plastic, epoxy, polyurethane, and waterborne paints. For nighttime visibility, retroreflective glass beads or ceramic beads are embedded in the coating. Durability depends on material choice, traffic volume, climate, and maintenance; markers may wear or fade and require reapplication at intervals.

Standards and guidelines, issued by national or regional authorities, govern linemarking design and installation. They specify colors, line types, minimum widths, spacing, reflectivity, and placement relative to signs and intersections. Examples include the Manual on Uniform Traffic Control Devices in the United States and equivalent regulations in other regions.

Overall, linemarking enhances road safety and traffic efficiency by providing clear, predictable guidance to drivers and pedestrians. In parking facilities and other non-road environments, it helps organize space and manage access and turnover.
