The reducing road speed, also called reducing badeness road speed, is placed on the road surface and intended to maintain speed in certain areas.
Why are they placed, and what effect does a speed bump have? As their name suggests, they are placed to reduce speed, and as we have already told you, the effect they cause is discomfort for both the driver and the occupants of the vehicle when they are exceeded at a speed higher than the speed allowed in said section. Check how much do speed bumps cost?
These speed reducers have specific placement and design criteria. If you want to know more, keep reading and discover more details.
Speed Reducers Design
Regarding the design of the reducers, we focus on telling you about the construction materials and their geometry:
Materials
The materials for the manufacture of a road speed reducer must be of quality since it must be guaranteed that the reducers have a long useful life, do not deform, and are stable.
But what materials are recommended? Quality concrete for raised pedestrian speed bumps and high-quality rubber or plastic material for ‘donkey’s back’ speed bumps. These, in addition, must be fastened to the asphalt through screws or chemical adhesives that guarantee that they are perfectly fixed.
Geometry
Taking into account the geometry, there are different types of road speed reducers:
- Trapezoidal cross-section speed reducers: these reducers also fulfill the function of pedestrian crossings and are slightly elevated.
- Donkey Back Speed Reducers: These are the circular segment cross-section speed reducers.
What Are Cross Alert Bands (BTA)?
You’ve undoubtedly heard of Cross-Alert Bands (BTA). They modify devices for the road surface that use transmission of vibrations or noises derived from their action on the vehicle’s suspension and damping system to give warnings to drivers.
