What is a Speed Bump?

[GemmaLee]

Speed bumps, also known as speed humps, are traffic facilities installed on roads to slow down passing vehicles. They are typically placed at intersections, industrial and mining areas, schools, residential entrances, and other sections where vehicle speed reduction is necessary or where traffic accidents are prone to occur. They serve as specialized safety installations designed to reduce the speed of both motorized and non-motorized vehicles. Below is a detailed introduction: 1. General Classification: Based on their shape and function, speed bumps can be categorized into the following types: speed humps, speed tables, raised crosswalks, circular speed bumps, and solar-powered speed bumps. 2. Material Classification: By material, they can be divided into two types: rubber-made and cast steel-made.
