Abstract
A Warning Bump traffic safety device comprised of a base which is inserted over traffic cones or barrels and a strip and extensions, generally trapezoidal in cross section, attached to the base which extends into the roadway which causes both an audible and sensory warning to motorists driving over these strips. This traffic safety device is typically deployed in construction work zones in the buffer and work areas to provide additional warnings to both drivers as they approach a construction work area and additional warnings to both drivers and construction workers if a driver encroaches into lateral buffer area in the work zone. These traffic safety devices also tend to stabilize the cones and barrels.
