Speed Bumps And Speed Humps
No matter where people and cars are, traffic safety is highly concerned. In the vicinity of playgrounds and schools, parking lots and multi-purpose areas, aggressive driving is a safety risk for pedestrians. Slowing down is one way to protect residents in these areas. The slower traffic speed not only reduces the possibility of accidents, but also reduces the chance of death in the event of an accident.
Both speed bumps and humps help encourage safe driving in pedestrian zones.
Although speed zones are usually set up to encourage safe driving, the posted restrictions may be missed or ignored, so the traffic slowdown in these areas is often combined with the physical design of the road or the environment.
Speed bumps and speed humps are vertical obstacles used in traffic management-bumps in the literal sense, bumping overly fast vehicles. They are the most commonly used structural traffic calming elements. They can be made of asphalt, concrete, plastic, rubber or metal. Although these metrics are related and have many of the same benefits, they are not interchangeable solutions: they are suitable for different applications.
Speed humps, sometimes called road humps or undulations, are used in speed zones of 10-15 mph. They often appear on local streets or connecting roads. Traffic needs to be smooth, but speed can endanger pedestrians. Playgrounds and school areas often use these for traffic management.
When the car passes the speed hump at the speed limit, it will produce a slight shaking feeling. If a car is driving at an unsafe speed, the hump will shake the vehicle and the contents of the car, making the people in the car uncomfortable and destroying the cargo. These obstacles usually cross the lane in which they are located. In this way, vehicles are encouraged to pass over them with two wheels, reducing the possibility of bottoming out.
Speed humps come in different shapes and travel lengths. These factors affect the discomfort experienced in speeding vehicles. The travel length is between 3-20 feet. Speed humps are usually connected in series, passing through a long corridor to keep the speed down.
These vertical deflections are not a good choice for trunk lines, emergency routes, or any street, it is easy for the car to escape the shoulders of hump driving. Because of this, they are usually installed in local urban environments with one or two lanes, where there are restricted and closed sewers. If speed humps are installed in areas where there is shoulder, they are usually paired with bollards or other obstructions to prevent the car from leaving the road.
Speed bumps are a more radical traffic stabilization option than speed bumps, so they are useful in places where pedestrians and cars coexist closely, such as parking lots and driveways. Speed bumps usually reduce traffic speeds to 2-10 miles per hour, giving people and cars time to react safely to each other. Speed bumps are rarely used on public roads because they require vehicles to stop at close distances past them and cause damage to cars traveling at normal speeds.
Speed bumps may be 2 to 4 inches high, but they travel much shorter distances than speed humps. These obstacles will be pressed under the tires in less than half of a full wheel rotation, and the standard width is between 6 inches and 2 feet. The ratio of height to distance traveled will cause a sudden bounce in the vehicle, causing passengers and cargo to shake. Since the speed bump is always much smaller than the vehicle passing over it, each axle will pass separately, which means that a speeding car will experience two substantial shocks.
Speed bumps, like their more stable brothers, can be placed at intervals to keep slowing down. They are often separated wisely because they are more uncomfortable at any speed and are used in smaller geographic areas.
