TRAFFIC CALMING PROGRAM
Level 3 Traffic Calming: ROAD HUMPS
Road humps are a smaller version (50 mm (2 inches) high as opposed to 75 mm (3 inches) high) of speed humps. The purpose of road humps is to alert motorists to the residential area and their driving characteristics rather than as a speed attenuator or bypass traffic deterrent.
A road hump does not provide a significant jarring sensation to a motorist. Rather, it provides a subtle disruption which may make motorists more aware of their surroundings - similar to rumble strips.
The application of road humps is similar but less restrictive than the speed hump. The applicable grades are up to eight percent (8%) and the warrant criteria requirements are not as restrictive.
IMPLEMENTATION
- May be applicable on roadways up to eight percent (8%) grade with less restrictive application of warrant criteria. Impact to speeds and as a bypass deterrent is minimal. However, impacts to motorist awareness may be increased
- Use the following guidelines for installation of speed humps vs. road humps
