EVOLUTION OF SPEED BREAKER

Abstract

The easiest and traditional way to control the traffic is calming devices, which are well known as vehicle speed reducers, and these calming devices used to avoid accidents. Basically, two types of vertical as well as horizontal speed breakers are used around the world to quickly reduce speeds at reasonable levels for law enforcement. Some defective built and irregular speed breakers still cause several incidents, so these speed breakers are still in the glare of objections, but today the world is heading towards smart speed breakers that, compared to conventional speed breakers, may be safe and more environmentally friendly. The smart and new speed breakers across the globe have been examined in this review report.
