If the primary function of speed bumps like in Unimat traffic is to reduce the speed of vehicles traveling on the road, their objective is, above all, linked to road safety. Indeed, since their installation on the roads, the devices made up of speed bumps and traffic signs have made it possible to reduce the number of fatal bodily accidents between motor vehicles, pedestrians, and cyclists.
In addition, the risk for a pedestrian of being killed in a collision while crossing a lane is 80% when the impact speed is 50 km / h, whereas it is not. More than 10% when the impact speed is 30km / h.
Installation Of Speed Bumps In Built-Up Areas
Trapezoidal type retarders can only be installed in built-up areas, between entry and exit signs of a municipality, on service areas, and forest roads. They are prohibited on roads carrying more than 3,000 vehicles per day, such as motorways, and on those used by buses or serving emergency centers.
Less restrictive in terms of layout and traffic conditions, speed reducers such as cushions and platforms can be used on tracks carrying significant heavy goods traffic. They are suitable for public transport traffic. Retarder indication panel and the speed limit at 20 km / h
Road Users And Speed Bumps
The installation of alternative cycle paths parallel to the road is a response regularly provided by Road Town planners to deal with cyclists ‘ discomfort when faced with speed bumps. In addition, many professionals agree that these arrangements do not facilitate the movement of agricultural machinery and heavy goods vehicles because they do not always consider the size of these professional vehicles. Finally, when they are located in built-up areas near homes, speed bumps generate significant noise pollution, disturbing residents.
When approached at too high a speed, retarders can turn out to be real sources of serious accidents, especially for drivers traveling in a vehicle with shock absorbers in poor condition or poorly maintained. Like all mechanical components, they must be regularly checked, repaired, and maintained in good working order to avoid breakdowns. Failure to comply with an instruction linked to a slowing down or even stopping sign may result in a fine.
