The organization of compliance with speed limits plays an important role in urban improvement. In order to forcibly limit the speed of movement, in 2006 state standards DSTU 4123: 2006 "Traffic safety. Device for compulsory reduction of the speed of road transport equipment on the streets and roads. General requirements" were created. Starting from 2020, a new DSTU 4123: 2020 "Road safety. Means of calming traffic. General technical requirements" comes into force, from this moment DSTU 4123: 2006 ceases to be valid.
Speed bumps in the form in which we are used to seeing them on the roads - yellow-black protruding irregularities, were registered in DSTU 4123 of 2006. And until now, speed bumps according to DSTU 2006 are widespread both on the territory of Ukraine and abroad.
Since 2020, speed bumps have changed their form and common name in state standards. The new type of speed bumps is called the "Berlin pillow", and in the DSTU it is registered as a road hill. These measures are designed to improve road safety and are rooted in European public road development practices.
The Berlin cushion does not occupy the entire width of the road section, but only the central part of it. This is to reduce the noise level from passing trucks with wide wheelbases when the truck rumbles while passing a speed bump. At the same time, the Berlin airbag forces passenger cars to slow down.
The Berlin pillow is more gentle for the car when driving through artificial road bumps than a speed bump. Also, the Berlin pillow, due to its width, is more resistant to destruction by harvesting equipment.
