What are the regulatory requirements for the installation of speed bumps on urban roads?

[VonIsabella]

National traffic technical regulations stipulate that traffic facilities applied to roads, including speed bumps, must be manufactured according to specific specifications. The regulations require the long side of speed bumps to be 250~500mm, the wide side 200~400mm, and the height 3~10mm. The height of speed bumps is particularly critical, as excessively high speed bumps may cause traffic accidents when vehicles pass at high speeds. The purpose of speed bumps: Speed bumps prompt drivers to reduce speed. In some harsh environments, such as mining sites, where heavy vehicles are the main traffic and the flow is high, the quality and material of speed bumps are undoubtedly paramount, but their specifications also play a significant role. Speed bumps of different specifications exhibit noticeably different capabilities in resisting pressure and impact.
