Bumper Thumper Pop-up Sign

This device serves to communicate directions as well as ‘grab’ the attention of drivers approaching checkpoints. Its dimensions are approximately: 42in. x 27in., for the frame; and 36in. x 24in., for the attached sign. This hybrid sign/speed bump, made from Lexan and other high impact materials, causes no damage to the vehicle on impact. Instead it alerts the driver via a bump (caused by driving over the device) and a loud noise (caused by the impacting sign). The intended use of this device is to communicate to the attentive driver that they should slow to a specific speed and change lanes. To the inattentive driver, this device will be certain to bring their focus to their surroundings. Spring loaded hinges return the sign to the upright position after the vehicle has driven past. AFRL is interested in Cooperative Research and Development opportunities to demonstrate a possible manufacturing capability for military and civilian use.
