The AASHTO-FHWA Joint Agreement for the Implementation of MASH 2016 requires that any roadside safety hardware (guide rail, bridge rail, transitions, attenuators, etc.) to be installed on the National Highway System must be MASH-compliant. Transitions were not previously required to be crash tested, so the New York State Department of Transportation (NYSDOT) designs needs to be.
The consultant research team (C2SMART) will be composed of researchers from New York University, Rutgers University, and RoadSafe LLC. The team will work with the crash tester as a subcontractor, with crash testing final detailed scope, exact budget, and refined timeline defined on a task-by-task basis by the consultant and authorized by NYSDOT. The crash tester for this project is envisioned to be Calspan Corporation of Buffalo, NY, who have expressed interest, budget estimates in line with funding availability, and ability to complete the crash testing tasks as defined in the Scope of Work.
The objective of this project is to determine if the designs are MASH-compliant and will provide recommendations for modifications if any are not.
Goal: The Consultant shall perform finite element modeling (FEM) and three crash tests on roadway safety hardware to determine if it is compliant with the 2016 Manual for Assessing Safety Hardware. If it is not found to be compliant, provide modification recommendations backed by modeling results.
Over the course of the project, C2SMART will evaluate:
- NYSDOT’s Three-Rail Steel Bridge Railing (w/Curb),
- NYSDOT’s Four-Rail Steel Bridge Railing (Curbless),
- NYSDOT’s Transition from Box-Beam Guide Rail to Three-Rail Steel Bridge Railing (w/Curb),
- NYSDOT’s Vertical Faced Concrete Parapet (10” thick, no sidewalk, w/fence),
- NYSDOT’s Transition from Box-Beam Guide Rail to Vertical Faced Concrete Parapet (Face Mounted),
- NYSDOT’s Precast Single Slope Concrete Barrier,
- NYSDOT’s Single Slope Concrete Barrier,
- NYSDOT’s Transition from Box-Beam Guide Rail to Single Slope Concrete Barrier,
- NYSDOT’s Transition from Box-Beam Guide Rail to Vertical Faced Concrete Parapet (Blunt End), and
- NYSDOT’s Flared Transition from Box-Beam Guide Rail to Single Slope Concrete Barrier.
Finally, C2SMART will prepare a final report summarizing the research, methodology and results, including all tasks performed, deliverables, findings, and implementation strategy, as applicable.
