Abstract

A transition between light- and heavy- post W- beam guiderail was evaluated through two full- scale crash tests. The transition consisted of lowering the rail height from 30 to 27 in. and reducing the spacing of the light posts as the heavy- post section is approached. Test results were generally acceptable in terms of NCHRP criteria.
