AN EVALUATION OF SELECTED TRUCK MOUNTED ATTENUATORS (TMA'S) WITH RECOMMENDED PERFORMANCE SPECIFICATIONS

The objectives of this project were to (1) assess the performance of several truck mounted attenuators (TMA's) and then (2) develop and propose the criteria that define an "acceptable" TMA. This report is the first of three volumes. Its purpose is to detail the work conducted during the course of the study, and to present the study findings, conclusions and recommendations. More specifically, this volume provides an overview of the study, along with the results obtained during crash, vibration and moisture tests on seven different makes and models of TMA's. The volume is divided into five main parts: (1) Introduction (a brief review of the development and crash testing of TMA's since 1972); (2) TTI Assessment of Individual Makes and Models of TMA's; (3) Summary of Findings on TMA Performance; (4) Proposed TMA Certification Procedures; and (5) Recommendations.
