| Abstract | This report assesses crash characteristics of automated driving systems (ADS) vehicles to understand their safety consequences, as well as differences in vehicle kinematics when striking roadside devices compared to traditional vehicles. Because of the variety of roadside hardware, different ADS vehicle sizes\ and diverse impact configurations, finite element (FE) crash simulations were deemed the most effective approach. The project was conducted by the Center for Collision Safety and Analysis at the George Mason University (GMU), which has developed several vehicle FE models including a 1,100-kg small car model, a 2,270 kg pickup truck model, and 36,000 kg tractor-trailer model. These have been validated using full-scale crashworthiness as well as FHWA roadside hardware tests. Using these models, GMU conducted several studies for FHWA, State transportation departments, and roadside hardware manufacturers that investigated and improved the performance of roadside devices such as longitudinal barriers, crash cushions, sign support systems, work-zone devices, etc. GMU developed computer modeling methodologies and tools for roadside applications and created and validated computer models of several roadside hardware devices. |
