ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to traffic regulating speed bumps, and more particularly, to a novel design of a portable speed bump for temporary traffic regulation.
2. Brief Description of the Prior Art
The value of track bumps, also known as traffic humps, is well established. They provide a simple mechanism for necessitating drivers to reduce the speed of the vehicle. They do not produce a road hazard to the vehicle and thus have no significant negative side effect. There are times and circumstances under which it is necessary to install a road bump rapidly, or temporarily.
It has been proposed to produce traffic bumps that can be secured to a roadbed by an adhesive or fasteners such as nails or screws.
SUMMARY OF THE INVENTION
It has now been found that a portable traffic bump can be designed that is convenient to carry in a vehicle, position on a roadway, and that stays immobile in use, without being secured to the roadway. Thus, the traffic bump can be used on an as needed basis, and removed as desired. The traffic bump does not cause any damage to the roadbed.
