Book Description
An assortment of retrofit bridge railings and a retrofit transition were evaluated through full-scale crash testing. The assortment included: (1) a W-beam retrofit railing for a concrete baluster bridge railing (AASHTO performance level one); (2) a W-beam transition for the bridge railing above (NCHRP Report 350 test level two); (3) a double-tube pedestrian/bicycle railing mounted on the Illinois 2399-1 traffic railing (AASHTO performance level one); (4) a vandal protection fence on the New Jersey concrete safety shape bridge railing (AASHTO performance level two); and (5) a thrie beam retrofit railing, a Delaware design, mounted on a 203-mm-high safety curb (AASHTO performance level two and NCHRP Report 350 test level four). All of the designs demonstrated acceptable performance.

Book Description
The objectives of this study were to develop safer bridge rail and transition designs and to improve design guidelines. Ten bridge railings and two transitions were designed, tested, and evaluated in accordance with American Association of State Highway and Transportation Officials (AASHTO) requirements. The railings were designed using ultimate strength procedures and collision forces from earlier research. Design procedures, railing designs, and test results are presented. All designs demonstrated acceptable collision performance.

Book Description
Twelve full-scale crash tests were performed to evaluate the performance of a thrie-beam bridge-rail system. The system was tested both with and without a 6-in. curb, with rail height of 33 in.--measured from the deck--for both designs. Also tested were transitions from W-beam guiderail on S3x5.7 posts to thrie-beam guiderail on W6x9 posts, and from the thrie-beam guiderail to the bridge rail. This railing can be used on either new or existing structures, with or without curbs, and requires no attachment to existing railing or structural members. It offers a relatively low-cost railing and because it relies primarily on components common to other barriers, it minimizes maintenance inventory requirements.

Book Description
Three bridge rail systems were evaluated by crash test as installed on curved, superelevated downgrade alignment. Concrete safety shape barriers mounted vertical and perpendicular to the superelevation, and a tubular thrie beam system were evaluated. Test vehicles included an 1800-lb (820-kg) class mini-compact car, a 2250-lb (1020-kg) class subcompact car, and a 20,000-lb (9070-kg) school bus. Impact conditions for all tests were 40 mph (64 km/h) and a 15-deg angle (as measured at the curve tangent).
