Last month, the Government Accountability Office (GAO) released a report emphasizing the importance of properly maintaining guardrails and other hardware to road safety. Roadside safety “hardware” most often refers to guardrails and median barriers, but the GAO report also includes several other groups of road safety hardware, such as:
- “Longitudinal barriers, which include items such as guardrails and cable barriers and are intended to reduce the probability of a vehicle’s striking an object or terrain feature off the roadway that is less forgiving than the barrier;
- bridge barriers, which function as longitudinal barriers but are specific to bridge design;
- barrier terminals/crash cushions, which include items like guardrail end terminals that are intended to absorb or divert the energy of a crash into the end of a longitudinal barrier;
- support structures, such as sign supports, which are designed to break or yield when struck by a vehicle;
- work zone devices, which include a variety of items used in a work zone that are temporary in nature.”
In the report, the GAO explicitly states the objective of all kinds of roadside safety hardware, that goal being “when the hardware contains, redirects, or decelerates the vehicle to a safe stop without causing serious injury to the vehicle’s occupants or other people.” The GAO report also noted the discrepancies shown in a state by state survey. The survey demonstrated the inconsistencies in the crash testing results of such road safety equipment across different states. This is likely due to the lack of a monitoring program by the Federal Highway Administration (FHWA), a program that the GAO insists should be implemented to provide additional support on scheduled safety upgrades.
