Texas Rumble Strips

Rumble Strips in texas

Most Texas drivers are familiar with rumble strips. You might have only seen them along the side of the road, you might have encountered them while dosing off while you're driving, or you might have even driven a little intoxicated and accidentally drifted onto them.

Texas Rumble strips are devices designed to generate audible and tactile vibrations as vehicles pass-over them. They consist of raised (bumps) or lowered (divots) that cause breaks in the surface level of a roadway. They are often placed in proximity to the edge of a roadway, on the centerline of a roadway, or in the lane of a roadway. There are several different kinds of rumble strips:

• Raised Rumble Strips - are rumble strips that are created by the placement and forming of additional roadway material or by placing prefabricated materials on the finished roadway surface.
• Milled Rumble Strips - are a type of rumble strip that is ground (cut) into the finished surface of a roadway and constitutes a divot.
• Rolled Rumble Strips - are a type of rumble strip that is rolled into the finished surface of a roadway and constitutes a divot.
• Transverse Rumble Strips - are traditionally raised, and are placed in the lane. They generally traverse more than two-thirds of the travel path perpendicular to the direction of travel.
• Centerline Rumble Strips - are rumble strips that are installed along the specified roadway centerline.

In the first year that rumble strips were used on Texas highways, centerline rumble strips alone-reduced crash rates by 20%. Further research by the Texas Department of Transportation has revealed that rumble strips reduce run-off-the-road crashes by 50%. At only 12 cents per foot, rumble strips are a cheap, effective ways to prevent crashes, which in turn saves both people and the government money that would otherwise be spent dealing with these crashes.
