Under a Safe System approach, reaching the zero goal requires managing the circumstances of crashes such that the kinetic energy forces imposed on the human body do not result in death or serious injury. At an intersection, this is accomplished by influencing conflict points, speed, and crash angles, and considering exposure and complexity. Intersection projects are opportunities to explore how to apply Safe System principles to the project development planning and design decisions in support of reaching the zero goal, as well as a performance-based approach to safety. The Federal Highway Administration (FHWA) sponsored an effort to develop a Safe System for Intersections (SSI) framework and methodology, which represents a first step toward the development of objective and implementable analyses that reflect key Safe System concepts.

The Safe System assessment of an intersection can serve as an additional metric to inform alternatives analysis and identify an optimal solution for an intersection. The SSI method uses data that are typically available early in a project development lifecycle. In this webinar, you will learn about the SSI framework and explore the potential to apply the methodology within the decision-making process for intersection projects.
