Rumble strips are roughened surfaces that are either embossed or recessed. When a vehicle drives over them, they make a loud rumbling sound and vibration. They can be placed across traffic lanes to alert drivers that they are approaching a potentially hazardous location, such as a work zone or an isolated intersection. They are used along the shoulders or centerlines of highways to alert drivers that they are leaving their traffic lane.
Traffic barriers, sometimes called crash barriers, or Armco (barriers)—as an AK Steel (formerly Armco) genericized trademark—keep vehicles within their roadway and prevent vehicles from colliding with dangerous obstacles such as boulders, buildings, walls or large storm drains. Traffic barriers are also installed at the road side to prevent errant vehicles from traversing steep (non-recoverable) slopes or entering deep water. Traffic barriers are installed within medians of divided highways to prevent errant vehicles from entering the opposing carriageway of traffic and help to reduce head-on collisions. Some of these barriers, designed to be struck from either side, are called median barriers. Crash barriers can also be used to protect vulnerable areas like school yards, pedestrian zones or fuel tanks from errant vehicles.
