Abstract:

A successful full-scale vehicle crash test was conducted on a State Department of Highways and Public Transportation standard Metal Beam Guard Fence (MBGF) median barrier which had been modified to strengthen it in the vicinity of a median mounted luminaire support. Under similar crash tests the standard MBGF would have deflected laterally 1 ft (0.30 m) or more permitting the vehicle to snag or knock down the luminaire pole. The modifications to the median barrier consisted of widening the back-to-back spacing of the 10 gage "W" sections from 6 in. (15 cm) to 18 in. (46 cm) in a length of 18 ft 9 in. (5.72 m) in order to provide space for the luminaire pole. The 688.5 posts were strengthened by increasing the weld metal on the base and by adding additional posts in the transition. The transition was impacted by a 4720 lb. (1935 kg) vehicle at an angle of 15 degrees and speed of 61.9 mph (99.6 km/hr.). The vehicle was smoothly redirected without snagging or knocking down the luminaire pole. The barrier deflection was nil.
