Traffic safety is of heightened importance when the people and automobiles are in close proximity. It is always a safety issue for the pedestrians near the parking lots, hospitals, schools and multi use zones. In this context, reducing the speed is the only way available to protect people’s lives from rapid driving. Slower traffic speeds minimize both the chances of an accident and the possibility of death should one occur.
To promote cautious driving in pedestrian zones, both speed bumps and humps are effective.
Speed zones are often put up to promote safe driving. Still, since the written restrictions are often forgotten or ignored, the physical design of the highway or surrounding environment is typically used to reduce traffic congestion in these locations.
Speed bumps and speed humps are vertical traffic control barriers that bump in the road that cause the passengers of a car traveling too rapidly over them to be jolted awake. According to statistics, they are the most often employed structural traffic calming components on the road today. They may be composed of various materials, including asphalt, concrete, plastic, rubber, and metal. These measurements are linked and have many of the same advantages; yet, they are not interchangeable solutions; they are each good for a specific application in their own right.

On minor streets or connection roads, traffic has to move smoothly, but excessive speed may harm people, they are often observed. A speed hump, also known as road humps or undulations, is a traffic control device used in 10–15 mph zones. These are often used in traffic control in playgrounds and school zones.
When a vehicle passes over a speed hump at the legal speed limit, it will experience a moderate rocking feeling in the automobile. If a car is traveling at a hazardous pace, the hump will jolt the vehicle and its contents, causing pain to the people and inflicting damage to the cargo. These obstructions often extend beyond the confines of the lane in which they are installed. Encouraging cars to pass over them with both wheels reduces the probability of a vehicle bottoming out.
Speed humps are available in several different profiles and travel lengths. These considerations impact the sensation of pain caused by the fast vehicle. The distance traveled ranges between 3 and 20 feet. There is just one up-and-down motion created by a journey length longer than the vehicle, but a travel length less than the vehicle causes two rocking motions when each pair of wheels passes over. Most of the time, speed humps are positioned in a sequence to maintain the speed restriction throughout a lengthy stretch.
They are not suitable for main highways, emergency routes, or any roadway where a motorist may easily avoid the hump by driving on the shoulder. The result is that most of the time, they’re built-in one or two-lane small urban settings with curbs and closed sewers. Whenever speed humps are built in regions with a shoulder, they are sometimes paired with bollards or other obstructive measures to prevent automobiles from off the route.
When compared to speed humps, speed bumps are more forceful traffic calming solutions. As a result, they are excellent in areas where pedestrians and automobiles share space closely, such as parking lots and driveways. A speed bump often slows traffic down to 2–10 mph, providing both people and automobiles enough time to respond safely to one another when they come into contact. Because they require vehicles to come to a near stop to pass over them, speed bumps are seldom utilized on public roads, and they may cause harm to vehicles traveling at standard speeds.
Speed bumps may range in height from two to four inches, although they go over a far shorter distance than speed humps do. These obstructions lie beneath a vehicle’s tire for less than half of a whole wheel revolution, and their normal widths range from six inches to two feet in length. The height causes a sudden bounce in a vehicle to travel distance ratio, which may cause both people and cargo to be shaken. Because a speed bump is always far smaller than the cars traveling over it, each axle will cross individually, resulting in a car traveling at excessive speed receiving two significant jolts.
Like their more sedate cousins, speed bumps may be put at regular intervals to keep the speed decrease consistent. They are generally placed at strategic intervals because they are more unpleasant to drive over at any speed and serve a limited geographic region.
Speed bumps can deliver a jolt, which may explain why they have earned a variety of amusing nicknames across the globe. They are referred to as “dos-d’âne” in French, which means “humpback” in English. They are referred to as speed breakers in India, judder bars in New Zealand, sleeping policemen in the United Kingdom, and road turtles in the United States (Southern US).
Benefits & Cautions:
One of the most significant advantages of speed bumps and humps is that they retain their effectiveness as a deterrent regardless of how acclimated drivers get to their presence. For a short period, flashing signs or intermittent traffic enforcement might alter motorist behavior, but drivers often return to their former habits. One may choose to ignore a sign, but one cannot ignore the road underneath it. A speed hump or a speed bump causes the same pain for a motorist traveling too rapidly, regardless of whether it is their first or hundredth time passing over one.
A bump in the road is not always the best solution for calming traffic situations. Obstacles operate best when the driver is aware that they are approaching and begins to slow down before reaching the obstacle’s edge. Speed bumps and humps are often carefully marked with contrasting colors or reflective surfaces to promote visibility. Still, they must also be located in areas where drivers will see them approaching to be effective. Use of these devices amid a lengthy curve or on streets with grades more than 8 percent is not recommended. A steep incline may also alter the effective height of a speed hump or bump, causing it to have a greater impact than it was originally designed to have. Visibility may also be a problem in certain winter climes, particularly in areas where snowfall is heavy and local roads are not plowed.
On arterial or emergency routes where they might pose a safety threat, speed humps and bumps are likewise not advised for installation. A motorist may lose control of his or her car if these obstacles are encountered unexpectedly or while traveling at excessive speeds.
However, the most flexible instruments in the traffic management toolkit are those that are utilized in the correct context.
Materials and installation
Depending on their purpose, speed bumps and humps are often built of rubber or asphalt. Various materials such as plastic, metal, and concrete are also available.
These obstacles, often composed of rubber or plastic, are simple to put on pre-existing surfaces, allowing for a quick and efficient set-up. Both solutions are lightweight and may be deployed just for a short period. Snow removal in winter regions may be difficult by very restricted installations, particularly when several of them are put near together in series. Both rubber and plastic speed bumps can be removed to make these procedures more convenient.
As rubber has higher compression than asphalt or concrete, it may be advantageous to a vehicle that strikes it too rapidly, at an angle, or when it is low to the ground, as the vehicle is less likely to sustain damage as a result of the impact. Because of the increased compression, rubber obstacles of the same height are less efficient at delaying traffic than identical asphalt installations. As a result, rubber or plastic obstacles are not recommended for highways where heavy industrial traffic is constantly passing. On the other hand, Rubber is strong and long-lasting under typical circumstances, and it is affordable to purchase and install.
Municipal road workers or private paving firms are often tasked with installing asphalt or concrete speed humps. They must be precise and knowledgeable in the field, or else the installation might go wrong. In the hands of suitably skilled staff, asphalt may be used to create obstacles with certain shapes and travel lengths. Because both materials have less compression than rubber or plastic, they are marginally more successful at speed reduction than the other. On the other hand, asphalt and concrete will tend to wear and break over time and under various weather conditions.
To promote cautious driving in pedestrian zones, both speed bumps and humps are effective. Speed humps are beneficial in locations where traffic must move quickly, while speed bumps are good in tiny spaces where people and vehicles share space more evenly. Both need less preparation than other physical traffic calming systems such as roundabouts or one-way streets, and modular, prebuilt versions may be put quickly and cheaply on existing surfaces. Roundabouts and one-way streets are examples of such approaches. When placed in the proper context, larger speed humps and their smaller but more aggressive siblings, speed bumps, maybe traffic safety superstars when used properly.
