Abstract
Full- scale vehicle crash tests evaluated performance of typical work zone traffic control devices. Plastic drums used as channelizing devices, cones, tubes, and vertical panels performed well in most tests, presenting no hazards in terms of passenger compartment intrusion, interference with vehicle control, or threat to workers and other traffic from impact debris. Various nonstandard forms of ballast placed on top of or inside channelizing devices detracted from performance, and sometimes posed a severe threat to test vehicle occupant, workers, and other traffic.
