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

Implementation of MASH for Sign Supports, Breakaway Poles, and Work Zone Traffic Control Devices (Phases I-IV): the objective of this research is to develop guidelines for implementation of, and propose modification to, 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. The research includes 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 crashworthiness. MASH Crashworthiness of Luminaire Poles (Phases V-VI): There are two objectives: (1) determine the maximum height and weight of breakaway poles and hardware that will meet MASH requirements and (2) investigate if the criterion of a 4-inch-tall object on a 5-foot chord is appropriate for current vehicle fleet.
