Necessity of Humps

Necessity of Humps

Speed humps, also known as speed bumps, are raised sections of pavement designed to slow down vehicles. They are typically found in parking lots, residential areas, and school zones. The necessity of humps has been a topic of debate among civil engineers, as some believe they are an effective traffic calming measure while others argue they can cause more harm than good. In this essay, we will explore the necessity of speed humps from a civil engineering perspective.

One of the main reasons for the installation of speed humps is to reduce the speed of vehicles. According to the National Highway Traffic Safety Administration, speed is a major factor in almost one-third of fatal traffic accidents. By forcing drivers to slow down, humps can help minimize the risk of accidents and injuries, making roads safer for pedestrians and motorists alike. This is especially important in areas with heavy foot traffic such as schools and residential areas where children and elderly people are more vulnerable to accidents.

Another benefit of speed humps is their ability to control traffic flow. When drivers are forced to slow down, the chances of collisions and rear-end accidents decrease. This also leads to a smoother flow of traffic, reducing congestion on roads and improving traffic efficiency. Speed humps can also be strategically placed to discourage drivers from using certain roads as shortcuts, diverting traffic to more appropriate routes.

Speed humps can also be useful in reducing noise pollution. Vehicles traveling at high speeds tend to create more noise, especially when they are equipped with loud engines and exhaust systems. By reducing the speed of vehicles, humps can help to decrease noise levels in residential areas, making the environment more peaceful and enjoyable for residents.

However, there are some downsides to the use of speed humps. Some argue that they can damage vehicles and cause discomfort for drivers, especially for those with back or neck problems. In areas with heavy traffic, humps can also cause delays and increase travel time for drivers. Additionally, emergency vehicles such as ambulances and fire trucks may have difficulty navigating over humps, potentially hindering their response time to emergencies.

To address these potential drawbacks, civil engineers must carefully consider the design and placement of humps. The height, width, and slope of the humps should comply with standards to ensure they are not too harsh for vehicles and drivers. Proper signage and markings should also be implemented to alert drivers of approaching humps, allowing them to slow down gradually.

In conclusion, the necessity of humps lies in their ability to improve road safety, control traffic flow, and reduce noise pollution. However, civil engineers must also consider the potential negative impacts and carefully plan and design their installation. When properly implemented and maintained, speed humps can be an effective traffic calming measure and play an important role in maintaining safe and efficient roadways for all users.

Design Criteria of Road Humps

Design Criteria of Road Humps

Road humps, also known as speed bumps or speed cushions, are raised portions of the road that are intentionally designed to slow down traffic. They are commonly used in residential areas and school zones to improve safety for pedestrians and reduce the speed of vehicles.

The design of road humps is an important aspect of their effectiveness and efficiency. The following are some of the key design criteria that civil engineers consider when designing road humps:

1. Height and Length: The height and length of a road hump are crucial factors in its design. The height should be sufficient enough to force drivers to slow down, while the length should be long enough to ensure gradual acceleration and deceleration of vehicles. The ideal height of a road hump is between 3-4 inches and the recommended length is around 12 feet.

2. Ramp Angle: The ramp angle of a road hump is the slope that connects the level road surface to the top of the hump. The ramp angle should be steep enough to discourage drivers from trying to accelerate over the hump but not so steep that it causes discomfort or damage to vehicles. The recommended ramp angle is between 1 in 10 to 1 in 20.

3. Gradient: The gradient of the road hump is the incline before and after the hump. It is important to have a gradual and smooth gradient to ensure a comfortable ride for vehicles passing over the hump. A gradient of 1 in 25 or less is recommended.

4. Width: Road humps are usually designed to cover the entire width of the road, leaving no space for vehicles to avoid it. This ensures uniform speed reduction and avoids accidents from drivers trying to swerve around it. The typical width of a road hump is around 9-10 feet.

5. Spacing: The distance between road humps is also a crucial design factor. If the distance between humps is too short, it can cause discomfort and damage to vehicles. On the other hand, if the distance is too long, it defeats the purpose of having humps in the first place. The recommended spacing between two road humps is around 100 feet.

6. Material: Road humps are usually made of asphalt or concrete. Concrete road humps are more durable and long-lasting but are also more expensive to install. Asphalt road humps are cheaper and easier to install, but they may need more frequent maintenance.

7. Drainage: Proper drainage is essential for road humps to prevent water from pooling on top of them. Engineers must ensure that there is adequate slope and drainage channels to avoid any waterlogging.

In addition to the above design criteria, road humps must also comply with local regulations and be appropriately signposted to alert drivers. Regular inspections and maintenance are also crucial in ensuring that road humps remain effective and safe for all road users.

In conclusion, the design of road humps should be carefully considered to achieve their intended purpose of slowing down traffic and enhancing safety. By following these design criteria, engineers can ensure the effectiveness and durability of road humps in improving road safety.


In conclusion, the introduction of road or speed humps is a necessary measure to ensure the safety of drivers, pedestrians, and cyclists on our roads. These traffic calming devices have been proven to reduce speeding, accidents, and noise pollution in residential areas. While some may argue that they cause inconvenience or delays, the benefits far outweigh the drawbacks. It is important for communities to carefully consider the placement and design of road or speed humps to effectively achieve their intended purpose. With proper implementation and maintenance, road and speed humps can greatly improve the overall safety and quality of our roads.
