Speed ​​bumps: The speed bumps are mostly made of high-strength rubber, and the color is striking yellow and black, which is highly visible no matter in the day or night. It is mainly used for parking lot entrances and exits, up and down slopes, etc. It can remind drivers to slow down and prevent traffic accidents due to untimely braking. Some speed bumps are also inlaid with reflectors, which will reflect bright red or green light at night, which can attract the attention of drivers, reduce vehicle speed, and improve safety.

According to the different shapes and functions of speed bumps, they can be divided into the following types.

speed bump
The deceleration hill is a circular raised area in the center of the street or extending to the entire width of the street. It is 6-10 cm high and is set at a distance of 100-150 m. It is a commonly used speed control measure. There are four types of cross-sections of the deceleration hill: sine curve, circular arc, parabola and broken line. The advantages of the deceleration hill are: it can effectively reduce the speed of the vehicle, coordinate with pedestrians and non-motor vehicles, and it is convenient to implement.

reduction stage
A speed bump is an elongated form of a speed bump with a platform on its surface, usually long enough to accommodate a standard car. The advantages of the deceleration platform are: it can effectively reduce the speed of the vehicle, the fluctuation of the large vehicle passing through is relatively milder than that of the deceleration hill, and it can be coordinated with pedestrians and non-motor vehicles. The disadvantages are: it affects the beauty of the road, and it is easy to generate noise when the car passes, which increases the maintenance cost of the road.

road bump
The raised crosswalk is similar to the deceleration platform, with crosswalk markings drawn on its surface, barrier-free design at both ends, and used together with the crosswalk markings.

round
Combine the spikes with the round speed bump. There is a spike-sized slot on the top of the round speed bump. Fix the spike in the slot on the top of the round speed bump. Increases its nighttime reflective brightness. The disc-shaped design can effectively decompose the force and increase its compressive capacity. Installed separately, there is a space in the middle to facilitate the passage of bicycles and reduce the bumpy feeling of motor vehicles. When the driver passes through the speed bump, the driver can feel the speed bump visually and audibly, which is much better than the warning effect caused by the wheel pressing over the speed bump in the past.
