Title: Bridging Human Factors and Traffic Engineering to Improve Road Safety

Human factors play a foundational role in transportation safety, shaping how road users perceive, interpret, and respond to the roadway environment. Despite advances in geometric design, traffic control, and safety analysis, many collisions still arise from mismatches between roadway design and human capabilities or limitations. Modern safety philosophies such as the Safe System and Vision Zero frameworks emphasize creating transportation networks that anticipate real-world human behavior and minimize the consequences of error.

While traditional traffic engineering focuses on geometric design and regulatory compliance, it can overlook elements such as driver perception, cognitive workload, and decision-making. This presentation will demonstrate how integrating Human Factors and Traffic Engineering expertise can improve safety outcomes. Through case studies and applied research, we will explore how behavioral insights combined with engineering analysis can identify latent risks, enhance intersection design, and support the implementation of cost effective countermeasures.
