Proposed AASHTO Guidelines for Implementation of MASH for Sign Supports, Breakaway Poles, and Work Zone Traffic Control Devices

The objective of this research is to develop guidelines for implementation of, and propose modification, to the American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) for sign supports, breakaway poles, and work zone traffic control devices, including examples to demonstrate the application of the proposed guidelines. At the minimum, the research results shall include developing testing protocols that are validated by crash simulations and testing for families of related devices within the following three groups: (1) sign supports, (2) breakaway poles, and (3) work zone traffic control devices. For the purposes of this research, a family of related devices is a set of similar devices within one of the three groups that shares the same critical characteristics controlling the crashworthiness.
