Abstract:

Roadside safety hardware, such as longitudinal barriers and crash cushions, is part of the highway infrastructure that is used to protect an errant vehicle from crashing into fixed roadside objects in a well-controlled manner. Despite constantly improved design and standardized full-scale impact testing of the roadside safety hardware, more than 3% of U.S. traffic fatalities are caused by the inefficiency of the roadside safety hardware. Innovative designs are urgently needed to improve the level of safety and decrease the severity of accidents. In nature, many plants and animals are optimized to adapt to various overload conditions and have demonstrated superior impact-resistant and energy-absorbing capabilities. Careful examination of these biological structures may inspire a new generation of roadside safety structural designs. This project comprehensively reviews the structure-property-performance relationship of the exemplary biological materials and demonstrate that the strategies used by the various biological role models can be understood, abstracted, modified, and transferred to bio-inspired roadside safety hardware.
