ABSTRACT:

The Roadside Safety Pooled Fund members prioritized the investigation of current practices for installing w-beam guardrail terminals near curbs. Currently, there is little guidance on the effects on the impact performance of w-beam guardrail terminals caused by curbs. Therefore, the Texas A&M Transportation Institute (TTI) was tasked to review previous and on-going research on this topic and then collect information on current state of practice for installing w-beam guardrail terminals near curbs. Consequently, the objective of this project was to compile current literature and practices on w-beam guardrail terminals when located near a curb. This was achieved through a review of previous and on-going research projects and a state survey. The results of the survey were compiled and documented in this report. Appendix A shows the results of the survey in a raw format to provide information on specific design configurations. Appendix B shows the results of the survey in an aggregated format to provide information on current trends in the practice.
