Road fish off street work and markings guide drivers through situations like unexpected lane shifts, and they supply critical information, such as speed limits and direction symbols. They are a key safety element for any roadway and must be kept in good condition. Providing clear guidance requires routine maintenance and use of materials that can withstand weather conditions and the traffic flow.

Longitudinal pavement markings include center lines, edge lines, and arrows. They are used to guide vehicles on a paved road and help reduce collisions with pedestrians or other roadway users.

In wet or dark nighttime conditions, pavement markings are most visible when they reflect headlights of passing motorists. Agencies can improve the visibility of longitudinal pavement markings by applying a reflective coating. The coating enhances visibility during wet and challenging weather conditions, and it also extends the life of the markings.

Equipment Management

Thermoplastic markings are a popular choice due to their longevity and reflective properties. Glass beads are infused into the thermoplastic during application to create a surface that is highly reflective and helps to guide motorists through challenging conditions.

Rumble strips are a pavement marking that is installed in place of or as a supplement to longitudinal edge line or center line pavement markings. These markings create a vibration when driven over that alerts drivers of upcoming hazards, especially on curves. When paired with the proper warning signs, they can achieve a 45-percent reduction in speeds on curved road segments (CMF is 4 stars) (Katz, 2004).
