Now there are more and more speed bumps on the road, everyone must be curious, what kind of speed bumps are there? The following editors will introduce speed bumps to you. The generation of speed bumps plays a very important role in traffic safety. Today, speed bumps are now everywhere, special sections of higher highways, toll passages, communities, schools, medical institutions and other places. With its figure, as an efficient road safety transportation facility, it is now indispensable, but with the changes of the times, the speed bumps no longer only focus on safety, but from the perspective of comfort, convenience, beauty, etc. Higher requirements, therefore, to further improve the humanized design of the speed bump has become a trend nowadays. There are several types of speed bumps on the market.
1. Rubber speed reducer
Rubber speed reducer is designed according to the angle principle of the special rubber between the tire and the ground while the car is running, and is made of special rubber. It is a new type of traffic-specific safety setting used to reduce the speed of motor vehicles and non-motor vehicles at the entrances of highway crossings, industrial and mining enterprises, schools, residential quarters, etc. As long as the speed is slow, there is no problem with the deceleration zone, and basically no big deal.
2. Cast steel speed reducer
Made of special steel, the specification is 250 * 350 * 50mm, yellow and black color, and the load is more than 200 tons. It is often used in motor vehicle export areas of more than 200 tons such as highways, gas stations, city intersections, and toll stations. The screws left in the old installation position cause great wear on the vehicle tires, and even have potential safety hazards. This is what I encountered today, because I cannot install a new speed bump in its place.
Third, the deceleration mound
The deceleration hill is in the middle of the street or a raised area that extends across the width of the street. This is to show the rhythm of speeding!
Fourth, road protrusion
The raised crosswalk is similar to the speed reducer. Crosswalk markings are marked on its surface, and barrier-free design is set at both ends, which are applied together with the crosswalk signs.
Five, round speed bump
Combine the road studs with the round speed bumps. The top of the round speed bumps has a slot of the size of the road studs. Fix the road studs in the slot on the top of the round speed bumps to increase their brightness at night.
