New systems are continually emerging to address safety problems. Devices and practices improve in response to an incre

30、ased understanding of safety performance, a changing vehicle fleet, the emergence of new materials, and other factors. This second edition of the Manual for Assessing Safety Hardware (MASH) is the latest in a long series of crash testing guidance documents dating back to 1962. This update incorporat

31、es many changes from the previous edition. Some of the more significant changes include: A new matrix for cable barrier testing on slopes Modifications to several test vehicle dimensions Updated test documentation requirements This documents purpose is to encourage consistency in crash testing and e

32、valuation. Full-scale crash testing has been and will continue to be the most common method of evaluating the impact performance of safety hardware. Consistency in crash testing and evaluation benefits states, testing facilities, manu- facturers, and the public. Note that MASH addresses only the cra

33、sh testing of roadside safety features. It does not contain in- stallation or maintenance guidance, nor does it supersede any of the guidelines found in the AASHTO Roadside Design Guide. Implementation of this Manual by roadway agencies is outlined in an AASHTO/FHWA Joint Implementation Agreement. A
