Reliability-Based Analysis Of Horizontal Curve Design By Evaluating The Impact Of Vehicle Automation On Roadway Departure Crashes And Safety Performance, Omar Al-Sheikh, Seyed Hooman Ghasemi, Mohammad Jalayer

Henry M. Rowan College of Engineering Faculty Scholarship

Roadway departure (RwD) crashes are significant safety concerns, especially at horizontal curves. The design of these curves plays a crucial role in mitigating RwD crashes. Thus, a thorough understanding of the interaction between driver behavior, vehicle automation, and geometric design is vital. Substantive safety, which emphasizes the inherent safety in a road's design and function, serves as the foundation of our approach. Building on this, the study employs a safe system approach to investigate the performance of horizontal curves under both non-automated and partially automated conditions, using a reliability-based analysis focusing on Stopping Sight Distance as the primary driver demand. …
