Current Research Projects

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.
Consideration of Roadside Features in the Highway Safety Manual (NCHRP 17-54)
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.
Evaluation and Design of a TL-3 Bridge Guardrail System Mounted to Steel Fascia Beams
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.
Recommended Guidelines for the Selection and Placement of Test Levels 2 through 5 Median Bariers NCHRP 22-31
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.
