Abstract: This study explores the safety impacts of vehicle-to-everything (V2X) communication systems using probabilistic risk assessment (PRA) frameworks. Case studies on V2X interactions with Forward Collision Warning (FCW) and Automated Emergency Braking (AEB) in collision avoidance scenarios are developed using a web-based tool, Mobility PRA (MoPRA). Findings suggest that V2X-enhanced driver warnings improve crash modification factors (CMFs) by 7-8% beyond FCW and AEB functions. Future work aims to develop generic PRA models to capture other safety-relevant V2X applications.
