Implementation of MASH Surrogate Test Vehicles for Sign Supports, Breakaway Poles, and Work Zone Traffic Control Devices
| 项目名称： | Implementation of MASH Surrogate Test Vehicles for Sign Supports, Breakaway Poles, and Work Zone Traffic Control Devices |
| 摘要： | Historically, roadside safety features have been subjected to crashworthiness evaluations using a variety of impact test specifications and/or guidelines. The implementation of American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) has left state departments of transportation (DOTs) and manufacturers in a situation where a significant number of breakaway poles, sign supports, and work zone traffic control devices (herein called “Systems”) need to be evaluated for MASH compliance. The development of robust surrogate test vehicles, with an ability to largely capture vehicle deformation and penetrations as well as accurate system behavior, would reduce crash-testing costs and promote greater innovation for new products for manufacturers and DOTs. There is a need to provide a guide to aid in selecting the appropriate surrogate test vehicles and testing protocols to evaluate the crashworthiness of Systems. The objective of this research is to develop a guide for the implementation of surrogate test vehicles, including pendulums and bogie vehicles, for evaluation of Systems for MASH compliance and propose modifications to the AASHTO MASH for sign supports, breakaway poles, and work zone traffic control devices. At the minimum, the research results shall include the design and development of surrogate test vehicles, testing protocols, and validation based on simulation and laboratory 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 this research, a family of related devices is a set of similar devices within one of the three groups that share the same critical characteristics controlling crashworthiness. |
