Everything you need to know about speed humps!
Citizens often complain about speeding vehicles on roads and city streets. Although police enforcement can help people follow speed-limit regulations, such enforcement cannot be used on a regular basis due to the limitation of resources. This is where traffic management and traffic control devices come to help.
Traffic data shows that traffic control devices like speed humps, speed bumps, traffic barriers, speed cushions, speed tables, and traffic cones effectively slow down speeding vehicles and protect precious lives. They are accepted all over the world and are used in different areas like a school zone, slow zone, work zone or pedestrian zone.
Traffic safety and pedestrian safety tools come in many shapes, designs, colours, and materials. Each tool performs its unique role to create secure roadways and streets. One of these tools is the road hump that is often seen on residential streets.This article talks about road humps in detail. So dig into it to learn more about this beneficial tool.
What exactly is a speed hump?
A road hump is a raised section installed on the road pavement across the travel way. Like speed bumps, it is also often referred to as “sleeping policeman.” It is typically used in parking lots, city traffic lanes, school zones and high pedestrian traffic zones.
A road hump is available in varying lengths, heights and widths because each problem area has its unique needs and requires a specific kind of speed hump. It is available in different materials. Modern road humps are mostly manufactured from recycled plastic and rubber.
A speed hump is often confused with the speed bump, which is another tool used to maintain traffic-flow. However, from an operational point of view, both tools have a different impact on speeding vehicles. While road bumps slow down a vehicle’s speed from 5 to 10 miles per hour (mph), road humps reduce speed from 20 to 30 mph. They are considered a less aggressive speed control approach compared to speed bumps.
Road humps are often not installed in front of commercial areas like a store or office as they can cause inconvenience to the high volume of traffic on such busy roads. They are preferably used on high-risk residential streets and local roads where speeding vehicles and accidents are often observed.
