The road retarder is an integral part of France’s road landscape, particularly in built-up areas or private areas such as car parks, universities, and shopping centers.
But why are communities and businesses interested in setting up these plateaus and slowdown blocks? The first idea is logically to slow down vehicles using the lanes that have them for the sake of safety but not only. Let’s review the functions of speed bumps in general and the advantages of installing speed bumps compared to building plateaus and other speed bumps!
Streamline Road Traffic
Developing roads by installing speed bumps like speed bumps Boston does not have the sole objective of reducing the number of accidents and their severity. It is also a device that helps to control the speed to anticipate better and regulate the flow of vehicles.
Indeed, in heavy traffic, motorists and road drivers may accelerate and brake quite abruptly, which does not help improve traffic flow. On the other hand, when speed bumps are installed, road users know that it is in their best interest to limit their speed. They better anticipate the actions of other drivers and keep driving smoother, limiting traffic jams.
In addition, forcing cars to travel at maximum speed using speed bumps makes it easier for road managers to anticipate behavior. This allows them, for example, to adjust traffic lights so that traffic is as light as possible.
Reduce Noise Pollution
We think less about it, but the road speed bump can also be an exciting tool to lower the decibels in the street!
By effectively reducing traffic speed using speed bumps, for example, from 50 to 30 km/h, noise can be reduced by up to 4 dB (A). One condition, however, of promoting the installation of speed bumps that comply with standards and do not generate noise pollution.
This can be particularly interesting in municipalities crossed daily by a stream of many vehicles or in town, where traffic is almost continuous and can harm the well-being of residents. Of course, this positive effect of speed bumps remains limited since installing them on the noisiest routes such as motorways and other major roads, is unthinkable. Moreover, the noise reduction obtained may be considered insignificant to justify on its own the installation of such devices. However, we can see a significant collateral benefit.
