The Importance of Those Horizontal Lines You See on the Road
It is more possible that you’ve already seen or experienced passing through multiple horizontal lines on the roadways. Sometimes, we find them pretty annoying as it produces enraging sound and vibrates the entire vehicle when passing through them.
Those horizontal lines are called rumble strips. For us to know it better, they are not meant to give vehicles a speed boost. They are there to serve as a road safety feature that was first used back in the 1950s.
Generally, there are 4 types of rumble strips:
• The continuous shoulder
• The center line
• The continuous lane
• The traverse lane
The first three rumble strips are basically designed to warn you that you are not in the correct lane anymore.
Meanwhile, transverse rumble strips (TRS) warns you that you need to slow down due to an upcoming intersection, stopping point, toll plaza and sometimes even construction zone. Usually, they can be seen on expressways and multiple lane avenues where vehicles are faster. Here in the Philippines, it is also placed in the middle of the long boring highways such as the NLEX, SCTEX and TPLEX to keep drivers wide awake.
Over time, the use of rumble strips has been proven effectively. In fact, based on a study conducted by the U.S. Federal Highway Administration Research and Technology, TRS can be effective in reducing severe injury crashes.
Now you know the importance of those horizontal lines on our roadways. So, the next time someone ask you what is that for, you know the answer.
