AN ENERGY-ABSORBING FRANGIBLE-TUBE BRIDGE BARRIER SYSTEM

An energy-absorbing frangible-tube bridge barrier system has been installed on Interstate Route 84 on a 4 deg 10' horizontal curve. Accident data for equivalent periods prior to and after installation of the barrier indicate that reported accidents and personnel injuries have both been reduced by 50 percent since the installation, despite an approximate 25 percent increase in traffic during the observation period. The system is recommended for use on similar bridges where the probability of high-accident frequencies is known. /Author/
