Transportation Research Report TRP-03-49-95.
The safety performance of the Steel Backed Wood Rail to Bridge Rail Transition was evaluated as part of the federally sponsored Guardrail Testing Program II. During this evaluation, which included 5 full-scale vehicle crash tests, a number of modifications were made to improve the safety of the system.
The tests were conducted, reported, and evaluated in accordance with requirements specified for guardrail to bridge rail transitions in the National Cooperative Highway Research Program (NCHRP) Report No. 230, Recommended Procedures for the Safety Performance Evaluation of Highway Appurtenances. Upon implementation of the design changes described herein, the performance of the Steel Backed Wood Rail to Bridge Rail Transition was determined to be acceptable according to these guidelines.
