What are rumble strips and how they reduce road accidents
Road safety is a big challenge for India considering that every year we report one of the highest numbers of road accidents. And according to a World Bank report, India records the most number of deaths caused by road accidents. It is worth noting that a lot of accidents in India are caused by factors like poor road conditions, inaccurate road design, improper signage and warning signs, etc. The authorities have been undertaking a lot of measures to correct these and are also using some innovative ways to reduce the number of road accidents. One of these innovations is using rumble strips or rumble stickers. Now, chances are that you must have encountered rumble strips often while driving, especially over highways but wouldn't know the technical word for it. Allow us to help you know a little more about these.
Have you ever driven over a series of strips of small speed-breakers that made a vibration sound? Well, those are rumble strips. Rumble Strips are effectively mild indents on the roads that provide a tactile and audible warning to the driver. Whenever a car passes over rumble strips, the passengers experience vibration and increased road noise which is used to alert the driver. Rumble strips are usually placed before a lane merger, especially in the case of fast-moving traffic to alert a distracted or drowsy driver.
Rumble strips or stickers are also used in the middle of a road to demarcate lanes are along the shoulder of the road next to the curb or divider. The idea is to warn the drivers in case the vehicle veers out of the lane or gets dangerously close to the curb. The warning gives the drivers a chance to correct their action or reduce the speed of the vehicle and avoid a crash. According to studies, rumble stickers can significantly contribute towards reducing road accidents and are a safety standard in several countries.
The biggest benefit of rumble strips is that they are a low cost measure to ensure road safety. The drawback, however, is that they are a passive safety feature which is why several drivers tend to ignore them. But the next time you drive over rumble stickers, remember that they have been put in to warn you of a plausible risk.
