Following a review of the unacceptable test results on Missouri's transition to a concrete safety shape end section, MwRSF reasoned that similar test results would have obtained for a sedan impact with the transition configuration provided in Drawing No. 606.23D. Based on this fact, the need existed to develop a new approach guardrail transition that could be adapted to the thrie beam and channel bridge railing. In addition, the new design must be developed according to current impact safety standards which are based on crash tests with pickup rather than passenger-size sedans. The objective of the research project was to develop a new approach guardrail transition attached to Missouri's thrie beam and channel bridge railing. The transition system must be designed such that it meets the Test Level 3 (TL-3) safety performance criteria set forth in NCHRP Report No. 350, Recommended Procedure for the Safety Performance Evaluation of Highway Features.
