Finite element modeling and validation of a 3-strand cable guardrail system
Abstract The primary purpose of longitudinal safety barriers, such as cable barriers, is to contain and/or redirect errant vehicles that depart the roadway, hence keeping them from entering opposing…

Analysis and evaluation of a redesigned 3" x 3" slipbase sign support system using finite element simulations
TLDR
The predictions showed that modified 3″×3″ slipbase passes the NCHRP 350 safety Criteria, and the exact modelling techniques used in developing this slipbase are used to construct a FE model of the 3′×3′ slipbase.

Sign support height analysis using finite element simulation
TLDR
Finite element simulation is used to analyse the safety performance of roadside sign support systems and determines the effect of sign height on the amount of intrusion into the occupant compartment.

CRASH TEST EVALUATION OF ECCENTRIC LOADER GUARDRAIL TERMINALS
The test and evaluation of two W-beam guardrail terminal systems are described. The two terminals, though quite similar, are characterized by a 4.0-ft (1.5-m) flare offset and a 1.5-ft (0.5-m) flare…
DYNAMIC TESTING OF LUMINAIRE SUPPORTS WITH AN IMPROVED PENDULUM IMPACT FACILITY
The report presents the results of a staff study leading to the development of a validated pendulum substitute for the full scale tests of luminaire supports as required by current AASHTO…
A PRELIMINARY EVALUATION OF THE SYSTEM FOR INVENTORYING ROAD SURFACE TOPOGRAPHY (SIRST)
TLDR
It is concluded that the present SIRST system is usable; however, a more complete evaluation and further development are needed to adapt the system for highway department use.
End Treatments for Deep Beam Highway Guardrail
End treatments on highway guardrail serve two functions: (1) to make the end safe in case of an impact there, and (2) to provide anchorage in case of an impact adjacent to the end. Two basic…
Safety performance evaluation of secure mailboxes using finite element simulations and crash testing
TLDR
Finite Element computer simulations coupled with experimental testing is used to investigate the safety of secure mailboxes and establish some guidelines on their use and installation.
