Speed bumps, speed humps, and cable protectors are essential traffic safety devices designed to control vehicle speeds and protect cables in various environments. These products, ranging from rubber bumps to heavy-duty cable ramps, serve different purposes in managing traffic flow and ensuring the safety of pedestrians and infrastructure.
Heavy-Duty Cable Ramp
Designed for robust cable protection, the 5-channel heavy-duty cable ramp measures 35.5" x 17" x 2" and is capable of safeguarding multiple cables from vehicular and pedestrian traffic. This durable product is ideal for use in various settings, including parking lots, construction sites, and commercial areas where cable management and safety are paramount

Speed Bumps vs. Humps
Watch
Speed bumps and speed humps, while similar in purpose, differ significantly in design and application. Speed bumps are typically shorter and steeper, designed to slow vehicles to 2-5 mph, and are commonly found in parking lots and private driveways. In contrast, speed humps are longer and gentler, aiming to reduce speeds to 10-15 mph, and are more frequently used on public roads and residential areas.

The installation costs also vary, with speed bumps ranging from $1,000 to $1,500 per bump, while speed humps can cost between $2,000 and $5,000 each.1
Both devices contribute to increased safety by forcing drivers to reduce speed, but their effectiveness depends on the specific traffic management needs of the area.1 source
Sleeping Policemen Origin
The term "sleeping policeman" for speed bumps originated in England in the 1970s, reflecting their role as stationary traffic enforcers. This colloquial name was adopted after physicist Arthur Holly Compton invented "traffic control bumps" in 1953 at Washington University in St. Louis

. The first speed bump in Europe appeared in Delft, Netherlands, in 1970, with Britain soon following suit. The British Transport and Road Research Laboratory conducted a comprehensive study on vehicle behavior over various bump geometries in 1973, though at that time, speed humps were not permitted on public roads1

. For speed control, options include rubber bumps with molded reflective tape and cat's eye reflectors for increased visibility2
. Floor cable protectors offer versatile solutions for safeguarding wires in diverse settings such as parking lots, television sets, and commercial areas3
. These products are designed to withstand challenging conditions, including sunlight, humidity, and heavy vehicle traffic, while maintaining their integrity and effectiveness in promoting safety.3 sources
