Speed bumps are a class of traffic calming devices that slow traffic with vertical deflection. Speed bumps are also called speed humps, speed cushions, and speed tables. Some examples are listed below. In addition to bumps, you might also see other types of traffic calming devices, such as speed hump signs. Despite their common names, they do differ from one another in several ways. In addition to improving safety, they also reduce collisions and noise pollution.
Less aggressive traffic calming option
Speed bumps are a less aggressive traffic calming method that many cities have used to improve safety. They slow vehicles by forcing them to travel at a slower speed, such as two to ten kilometers per hour. These devices are most effective in areas where cars and pedestrians share the same space, such as parking lots and sidewalks. In addition to slowing traffic, speed bumps can also improve pedestrian safety by requiring drivers to stop almost completely.
Researchers have also studied speed humps in cities like San Antonio, Texas. They found that they reduce average and very high speeds by approximately 7%. They also noted that humps may have different effects on vehicles of different sizes. The biggest drawbacks of speed humps, according to the NHTSA vehicle speed report, are the noise, height, and fewer humps than other methods of traffic calming. However, the researchers concluded that speed bumps are an effective traffic calming method and that many communities are using them to improve safety.
Speed humps are one type of traffic calming technique that can significantly reduce crashes. Their effectiveness depends on the location and height of the humps. In urban settings, they are most effective on local streets that are less than two lanes and are not used on emergency routes or arterial roads. They are commonly installed along with curbs and other obstructive measures. They can also be effective in deterring cut-through traffic in residential areas.
In addition to humps, speed bumps can also reduce the speeds of vehicles. They slow cars to about five miles per hour or less and are used primarily in areas with slower traffic speeds. The humps are usually wider and higher, but they have the same effect as speed humps. They also create the same level of discomfort for drivers, unlike flashing signs that cause immediate changes in driving behavior.
Both of these traffic calming measures are effective at reducing speed and increasing pedestrian safety. Some of these techniques include lane narrowing, on-street parking, and buildings close to streets. Other methods include incorporating the physical design of the roadway itself. While both methods are effective, speed humps are more aggressive and require drivers to approach them from a distance. This type of traffic calming method can be easily converted into a pedestrian walk when the space allows it.
Improves pedestrian safety
Although they have many benefits, speed bumps are not always effective in reducing traffic speeds. The effect of speed humps on pedestrian safety is greater on major roads. For example, pedestrian crashes are reduced per mile of the roadway when drivers pass speed humps near them. In addition, pedestrian injury severity is reduced as well. In addition, speed humps can improve safety for pedestrians and vehicles in residential areas. Read on to learn more about the benefits of speed bumps.
As a result, the Institute of Transportation Engineers defines traffic calming as a technique that alters driver behavior to improve pedestrian safety. Traffic calming is often implemented to reduce the negative effects of motor vehicle use by enhancing conditions for non-motorized street users. While speed bumps are not a permanent solution to the problem, they do improve safety and comfort for pedestrians. These measures are effective countermeasures for conflict with motor vehicles.
In Ghana, traffic calming measures such as speed bumps have become widespread. Since traffic enforcement is generally lax, 90% of vehicles exceed the 50-kph limit. Unfortunately, pedestrian deaths account for 40% of all road deaths, making speed calming measures necessary. Pedestrian safety benefits have been documented in Ghana. And while they can be effective in curbing traffic, they should be used cautiously, as they can cause substantial discomfort to vehicle occupants.
In addition to speed bumps, other measures can also reduce pedestrian fatalities and injuries. Temporary mid-block islands can slow speeds as much as speed humps do. They can also reduce the volume of pedestrians crossing a highway. Ultimately, though, the most effective way to reduce the number of pedestrian-vehicle accidents is to create awareness about the dangers to road users and pedestrians. But the effectiveness of traffic calming measures depends on how well they are implemented.
Reduces collisions
The installation of speed bumps has the added benefit of improving pedestrian safety. The bumps reduce the frequency and severity of collisions by passively reducing the number of vehicles that exceed speed limits. Hence, they are an effective way to improve pedestrian safety in residential and high-traffic areas. Read on to discover more about the benefits of speed bumps. Weigh your options carefully.

Studies on the safety of pedestrians have shown that speed humps have a positive effect on reducing childhood pedestrian injuries. A recent study conducted in San Francisco found that speed humps reduce collisions with pedestrians by 37.5%. This reduction is encouraging and supports further research on pedestrian injury prevention. These studies have demonstrated the benefits of speed humps and have paved the way for traffic engineering departments to consider their installation.
Although speed humps are expensive, they are among the most cost-effective methods of traffic safety. Installation of speed humps costs an average of $2,600, while raised medians cost more than $13,000 to build. Furthermore, speed humps are an excellent way to improve traffic flow and reduce collisions. This safety feature is also beneficial for pedestrians and cyclists. Speed humps are the most common safety feature for pedestrians and cyclists.
Studies have shown that speed humps can significantly reduce the speed of vehicles. The average speed of a vehicle traveling over a speed hump is reduced by between twenty-four and thirty-two kilometers per hour. Moreover, the speed reduction effect may depend on the posted speed limit, the number of humps, and the site conditions. Furthermore, speed humps may reduce collisions with pedestrians by 20 percent or more.
The NHTSA’s Vehicle Speed Report found that speed humps have a significant impact on traffic. They can reduce both average and very high speeds. In Seattle, for instance, where the humps were installed at 113 intersections, the number of accidents that occurred was reduced by 94 percent. However, speed humps had little effect on crashes in other jurisdictions, where there were only eight or fewer intersections. Moreover, these humps are effective at reducing collisions even after drivers become accustomed to their presence.
Increases noise pollution
The installation of speed humps has been frowned upon by many because they increase noise and pollution. While the intended purpose was to reduce traffic speed, the reality is that they have many unintended consequences. Besides making the road less safe, they can damage the suspension of cars and increase fuel consumption. Furthermore, some drivers have reported that these bumps exacerbate back problems. Many emergency services have also been complaining about speed bumps. Furthermore, speed humps have been a part of the City of London’s strategy to make streets safer for pedestrians. This includes a new road design manual, a safe-streets law, and a raised intersection in East Rock. But despite its many benefits, speed bumps have proved to be a complex issue.
One study suggests that the installation of speed bumps can increase noise pollution. This was confirmed by another study in the Netherlands. It found that the equivalent noise levels of vehicles at 20 meters from a speed bump were 1.2 decibels higher than those at eighty meters. Furthermore, these bumps may increase noise pollution, which is particularly detrimental if they are placed near public places and schools. The implications of these results should be studied thoroughly when planning the installation of speed humps near these sites.
Another study concluded that speed humps increase noise pollution in residential neighborhoods. The researchers studied eight test road sections in Denmark, which were designed for four different speeds. In addition to measuring noise levels at the humps themselves, they also measured noise near them, and at 10 meters before and after the humps. Vehicle noise was categorized into four categories, depending on whether it was generated by a car or a motorcycle.
However, not only do speed humps increase noise, but they also affect emergency response times. They hinder emergency response times, reduce property values, and discourage safe driving. Furthermore, the noise generated by vehicles may result in spinal damage or aggravate chronic backaches. This means that speed humps increase noise pollution, and should be avoided where possible. In addition to causing noise, speed humps also cause increased fuel consumption. That means more money and time for local municipalities.
