George Mason researchers begin crash tests of National Park Service bridge railings

Researchers at George Mason University are conducting crash tests to evaluate safety hardware used by the National Park Service on bridge railings. Cing-Dao Kan, professor and director of the Center for Collision Safety and Analysis, and Dhafer Marzougui, associate professor at the center, are working with hardware for which cost, maintenance and compatibility with the local setting are important considerations. Their aim is to determine whether the railings meet safety performance criteria, but the university’s grant announcement reports no test results or conclusions.

The planned study concerns railing safety devices used in national park settings rather than a broad survey of all bridge barriers. The announcement says the researchers will evaluate the performance of the hardware through crash testing. It does not identify the bridge sites, railing materials, vehicle types, impact speeds, test configurations or quantitative performance thresholds. As a result, the available information does not establish which specific designs or components will be tested or what level of performance any railing is expected to achieve.

Kan and Marzougui received $1,435,019 from the Federal Highway Administration for the project. Funding began in September 2026 and is scheduled to end in March 2028, placing the work within a defined research period. Because the announcement describes a funded program that is still underway, it documents planned methods and objectives rather than demonstrated safety benefits. The stated aim is to determine whether the safety hardware meets the relevant criteria, but the award alone does not show whether the railings pass those criteria.

The project highlights the practical factors being considered alongside crash-test performance: the cost of safety devices, the maintenance they require and their compatibility with local conditions. The announcement identifies both investigators as members of George Mason University’s Center for Collision Safety and Analysis in the College of Science. Further procedural details and outcomes were not supplied, and no claims about preventing crashes, reducing injuries or improving bridge-safety performance are supported by the available evidence at this stage.
