Should Speed Bumps Be Installed in Underground Garages?

If the ramp surface is constructed with deceleration ridges, there is no need to install additional professional speed bumps. However, they should still be installed at the entrance and exit. The function of speed bumps: By slightly raising the road surface, speed bumps aim to slow down vehicles and influence the driver's psychology, encouraging them to voluntarily reduce speed. Speed bumps are a specialized traffic safety device installed at intersections, industrial and mining enterprises, schools, residential areas, and other entrances to reduce the speed of motor vehicles and non-motor vehicles. Introduction to speed bumps: Speed bumps, also known as speed humps, are traffic facilities installed on roads to slow down passing vehicles. They are generally strip-shaped, but some are dot-shaped, and are primarily made of rubber, though some are metal. They are usually colored yellow and black to attract visual attention, with a slightly raised surface to achieve the effect of vehicle deceleration.
As someone who frequently deals with safety issues, I believe installing speed bumps in underground garages is quite necessary. Underground garages have poor visibility and many blind spots, making it easy for drivers to accelerate quickly, such as when turning or reacting too late to pedestrians. Speed bumps can force drivers to slow down. Experience tells me that placing them at high-risk areas like entrances, exits, and corners is particularly effective. Data shows that reducing speed to below 10km/h can decrease accident probability by 70%. Although some complain about the discomfort of the bumps, this minor inconvenience is worth it compared to the risk of personal injury. Additionally, underground garages often have children or elderly people walking around, and speed bumps provide everyone with extra reaction time. I’ve seen parking lots without them experience frequent accidents, while those with speed bumps show clear improvement. So, the key is using them in the right locations to enhance overall safety.
As an ordinary driver, I have mixed feelings about speed bumps. Every day when driving into the underground garage, those things keep jolting the car, causing significant wear to the tires and suspension, especially when frequently going up and down slopes—it's even more uncomfortable. The original design intention of underground garages is to be low-speed zones, where drivers should consciously slow down. Using speed bumps to enforce this feels redundant. I prefer clear markings or warning lights as reminders, which neither damage the car nor compromise effectiveness. In older underground garages, poorly maintained speed bumps can even damage the chassis, leading to costly repairs. From my personal experience, speed control relies more on the driver's attention, and installing speed bumps can actually be distracting. For safety considerations, speed bumps should only be placed in areas with severe mixed traffic of pedestrians and vehicles—they can be omitted elsewhere.
Working in the design field, I prefer using intelligent alternatives to replace speed bumps. Optimizing modern underground garage layouts is more important, such as curved ramps that inherently slow down vehicles, paired with colored coatings and reflective signs for visual reminders. Speed bumps are prone to damage, cracking easily when exposed to rain, making repairs troublesome and costly. The ideal approach is to install flexible buffers or speed limit sensors at blind spots and entrances, which automatically warn against speeding. This maintains smooth traffic flow while being eco-friendly. I recommend property management invest in these advanced tools, as they offer higher cost-effectiveness than physical speed bumps.
