Head-on test of cable guardrail.

This study contains information on the performance of the Minnesota wood-post triple cable guardrail under the head-on impact test conditions of 60 mph and 5 degrees using a 4500 lb. automobile. The average vehicle longitudinal deceleration level was well below the current FHWA acceptable level of 12 g's for a lap belted or lap and shoulder belted occupant. Also, the vehicle damage sustained was below the mean at which injury type accidents occur for an unrestrained occupant as established by the National Safety Council.
