Speed breaker specification
A speed breaker, also known as a speed bump or speed hump, is a transverse obstacle on a road designed to slow down traffic. Here are some common specifications for speed breakers:
Dimensions:
- Length: Typically ranges from 3 to 12 meters (10 to 40 feet)
- Width: Typically ranges from 0.5 to 1.5 meters (1.6 to 4.9 feet)
- Height: Typically ranges from 0.1 to 0.3 meters (0.3 to 0.9 feet)
Material:
- Concrete: The most common material used for speed breakers, as it is durable and can withstand heavy traffic.
- Asphalt: Can be used for speed breakers, but may not be as effective as concrete due to its softer nature.
- Rubber: Some speed breakers are made of rubber, which can be more flexible and quieter than concrete or asphalt.
Design:
- Gradual slope: The speed breaker should have a gradual slope to allow vehicles to slow down smoothly.
- Smooth surface: The surface of the speed breaker should be smooth to prevent vehicles from getting damaged or losing control.
- Edge treatment: The edges of the speed breaker should be treated to prevent damage to vehicles or pedestrians.
Speed reduction:
- The speed breaker should be designed to reduce the speed of vehicles by at least 10-15 km/h (6-9 mph).
- The speed reduction should be gradual to prevent sudden jolts or loss of control.
Safety features:
- Warning signs: Speed breakers should be preceded by warning signs to alert drivers of the upcoming obstacle.
- Illumination: Speed breakers should be illuminated at night to improve visibility.
- Pedestrian protection: Speed breakers should be designed to prevent pedestrians from being thrown off or injured.
Maintenance:
- Regular inspections: Speed breakers should be regularly inspected to ensure they are in good condition and functioning properly.
- Repair and replacement: Speed breakers should be repaired or replaced as needed to maintain their effectiveness.
Standards:
- Indian Road Congress (IRC) standards: The Indian Road Congress has established standards for speed breakers in India, including specifications for dimensions, material, and design.
- American Association of State Highway and Transportation Officials (AASHTO) standards: The AASHTO has established standards for speed breakers in the United States, including specifications for dimensions, material, and design.
It's important to note that the specifications for speed breakers may vary depending on the location, traffic volume, and other factors. It's always best to consult with local authorities or traffic engineers to determine the appropriate specifications for a specific location.
