Abstract:

A portable speed bump disc which can be easily deployed and removed from the roadway to control the speed of traffic. The disc preferably does not require mechanical and or chemical attachment to the pavement, and a plurality of discs, when placed in a staggered array on the roadway, can improve the safety of crews working in flagging operations, traffic work zones, or other situations where daily installation and removal of roadway warning devices may be required. Each disc is relatively small and light in weight as compared to conventional elongated rumble strips or speed bumps, and can be handled and deployed by a single worker.
