Traffic Calming Devices Overview
What are Speed Tables and Speed Humps?
Speed tables and speed humps are both traffic calming devices designed to reduce vehicle speeds and improve road safety. A speed table is a long, flat-topped bump that stretches across the entire road, with gentle slopes on either side. This design allows vehicles to gradually rise and fall as they cross, providing a smooth experience while still slowing down traffic. इसके विपरीत, a speed hump is a more rounded, elevated structure with a steeper rise. Drivers are required to slow down more abruptly when crossing a speed hump, making it more effective in forcing vehicles to reduce speed. Both devices are used in different settings based on the desired level of speed reduction.
Why Speed Control is Essential for Road Safety
You need traffic calming devices to keep roads safe. When cars move too fast, दुर्घटनाएं अधिक बार होती हैं. Speed tables and speed humps force drivers to slow down. This gives everyone more time to react and helps prevent crashes. Slower speeds also protect people walking or biking. By using the right traffic calming devices, you can improve safety for drivers, पैदल चलने वालों, और साइकिल चालक. You help create a safer community for all.

These markings point the same way as the traffic and help drivers see the device sooner. Each marking needs to be 12 inches wide and placed in the middle of a 12-foot lane. Speed humps should be 6 feet deep on both sides of a crosswalk or speed table, which is usually 10 feet deep.
Here is a simple guide to the main MUTCD rules:
| मांग | विवरण |
|---|---|
| चिह्नों | White ‘v’ shaped markings in each lane, 12 इंच चौड़ा |
| DIMENSIONS | Speed humps: 6 ft deep on each side; speed table area: 10 ft deep |
| Travel Lanes | Each lane should be 12 ft wide |
| Marking Width | 12-inch thick white lines |
| प्लेसमेंट | ‘V’ markings centered in each lane, pointing with traffic flow |
You also need to check your local laws before putting in these devices. Speed humps can only go on streets with a speed limit of 30 मील प्रति घंटे या उससे कम. You cannot put them where water drains down the middle, on steep hills, or on sharp turns. Streets used by buses, ट्रक, or emergency vehicles are not good for speed humps. Always make sure drivers can see the device from at least 250 फ़ुट दूर.
Ensuring Driver and Pedestrian Safety with Traffic Calming Measures
You want everyone to stay safe when you add traffic calming devices. These devices slow down cars and help stop crashes. Studies show that speed humps and speed tables lower the number of accidents, especially those with kids. Pedestrian safety gets better because drivers slow down and pay more attention.
