Selecting the appropriate pavement markings and retroreflectivity levels involves considering several factors to ensure safety and visibility for drivers, particularly at night and in adverse weather conditions. Roadway characteristics are a key factor. The type of roadway (e.g., Interstate, arterial, local) and its geometry (e.g., curves, grades) will influence the type and placement of markings. Traffic volume and speed are also important. High-volume, high-speed roadways require markings with higher retroreflectivity levels. Weather conditions play a major role. Areas with frequent rain, snow, or fog require markings with enhanced wet-nigh....
