Guidelines for Shielding Bridge Piers NCHRP (12-90)
The objective of this research is to develop (1) risk-based guidelines that quantify
when bridge piers should be investigated for vehicular collision forces or be shielded with a longitudinal barrier.
The objective of this project is to develop quantitative
measures that can be incorporated into the HSM to evaluate the effects of roadside designs and features on the frequency and severity
of lane departure crashes.
The objective of this research project
is the development of a cost-effective TL-3 post-and-beam type bridge rail system designed for mounting to the steel fascia beam of
Ohio rural bridges.
The objective of
this project is to develop risk-based guidelines for determining when and what type of median barrier is necessary based on the traffic
and highway characteristics at a particular site.
Evaluation of Proposed Design Modification to Oregon 3-Tube Bridge Rail
The objectives of this project were to evaluate a proposed
design modification for strengthening the Oregon 3-tube bridge rail and verify that the design change meets the FHWA criteria
for "inconsequential / positive" change based on NCHRP Report 350 Test Level 4 performance conditions.
