Difference Between Speed Bumps and Speed Humps
Both speed bumps and speed humps are vertical obstacles which are used in traffic controlling and management. These are the most commonly used structure to slow down the traffic. These can be made of asphalt, concrete, plastic, rubber or metal.
Speed humps are usually installed in places where the followed speed is 10-15 mph. These can be seen often on local streets, or connecting roads where the traffic moves smoothly. A speed hump gives a little rocking sensation to the car which passes over it. However, if the vehicle was over speeding, the hump will provide quite a jerk to the occupants and the items in the car. Therefore the drivers prefer to slow down their speed while crossing over a hump.
Speed bumps are more of an aggressive way to slow down the speed of the cars. These are most useful at places where pedestrians and vehicles move in near capacity to each other for example parking lots and driveways. A bump can generally slow down the traffic to 20 to 10 mph and gives both people and cars time to react safely to one another. These are not used on public roads because they need vehicles to come to a near stop which can do damage to cars moving at regular speeds. Speed bumps are two to four inches high and have shorter travel distance as compared to speed humps.
Why do we need speed bumps?
It is a common issue that drivers tend to over speed on various roads which can result in severe and fatal accidents. To reduce the number of crashes, speed bumps are installed which make the driver reduce the speed down to 10-15 mph and avoid hitting any pedestrians. A study from the Department of Transportation showed that a 40% speed reduction in vehicles was observed after installation of the speed bumps. This meant fewer accidents, and mostly the neighborhoods with kids were safe because of the slow speed of the incoming vehicles.
