Available in PDF, EPUB and Kindle. Book excerpt: "This project was concerned with the transition designs used between W-beam and thrie guardrail, and rigid bridge rail parapets or wingwalls. State designs submitted to the Federal Highway Administration (FHWA) were rated and designs selected for crash test evaluation. New designs were also formulated and subjected to crash test evaluation. Most of the crash tests were conducted with 4500-lb (2000-kg) cars at 60 mph (95 km/hr) and a 25-degree angle. Design drawings are presented along with recommendations for use of these transition designs. Guidelines for transition features are given and design procedures for independent end blocks are given. This volume, which is third in a series, contains appendix C, Ratings of State Transition Designs, and appendix D, Barrier VII Plots for Selected Transitions."--Technical report documentation p.
