Judging from the effects of speed bumps in recent years, speed bumps are a double-edged sword: scientifically setting speed bumps can effectively improve road traffic safety. On the contrary, it may have little effect or even become man-made roadblocks on highways. In order to make the deceleration belt play an effective role, we must pay attention to the following principles when formulating specific implementation plans:
1. The pertinence principle of cast steel speed bumps, that is, the type, shape, size, material, connection and installation methods of the speed bump must be analyzed and determined according to the specific conditions of the road section of the road grade, traffic flow structure, actual average speed, road alignment, pavement material Elements.
2. The principle of uniformity, the location and number of speed bumps must be based on investigations or road tests on real vehicles.
3. The principle of compatibility. Speed ​​bumps with greater compulsory force must be used in conjunction with other traffic safety facilities (reminder signs, markings, etc.) to ensure the safety and efficiency of use.
The content of the speed bump is briefly introduced here. Everything has two sides. When setting the speed bump, we try to follow the above principles to maximize the effect of the speed bump and reduce its negative effects.
