The Connecticut Truck Mounted Attenuator (TMA) was developed in the 1970s and a total of six crash tests were performed on the Connecticut TMA in 1976 and 1978. The testing program preceded the development of NCHRP Report 230, published in 1981, which specifies that vehicle acceleration data be filtered according to SAE J211b Channel Class 180. The six TMA tests were conducted according to the specifications of NCHRP Report 153 and Transportation Research Circular 191 and employed class 600 filters. In addition, NCHRP Report 230 requires occupant risk evaluation procedures which have been extensively revised from those presented in NCHRP Report 153 and Transportation Research Circular 191. In the report, the acceleration-time data associated with the six full-scale crash tests conducted on the TMA are re-analyzed to bring the output into conformance with NCHRP Report 230 procedures. Performance specification recommendations for TMAs are proposed.
