A Safe System-Based Framework and Analytical Methodology for Assessing Intersections

When: Tuesday, October 3, 2023 | 2:00 - 3:00 PM ET

This webinar is led by the ITE Safety Council.

Webinar Description:

In the United States, the Safe System approach represents a paradigm shift in how road safety is addressed. Foundational to the Safe System approach is that no person should be killed or seriously injured when using the road system, and that it is a shared responsibility by all parties involved to ensure this becomes reality. From a roadway infrastructure perspective, a Safe System approach involves managing the circumstances of crashes such that the kinetic energy imposed on the human body be kept at levels that are tolerable in terms of survivability and degree of harm. At an intersection, this challenge is characterized through managing speed and crash angles, as well as considering risk exposure and complexity. FHWA has developed a Safe System for Intersections method that can be applied at a project level and be incorporated into an Intersection Control Evaluation alternatives screening process to provide another metric for safety. This method focuses on conflict points, exposure, and the concepts of transferable kinetic energy and how these metrics can be used by planners and engineers alike to inform decision making for intersection projects.

A primary objective of this project was to develop a Safe System for Intersections (SSI) analytical methodology that intersection planners and designers can readily implement and that dovetails with the typical project development process—one that incorporates Safe System principles and relies upon commonly available project-level data. The goal is to provide a technical basis by which intersection planners and designers can apply kinetic energy management to common intersection projects in the U.S. However, the method’s framework provides flexibility to incorporate broader system efforts and characteristics (e.g., users, vehicles, speeds) in the future if supporting data
are available.

This webinar, supported by representatives of the Federal Highway Administration, the Florida Department of Transportation, and the Georgia Department of Transportation is sponsored by the ITE Standing Committee on Data-Driven Safety Analysis (DDSA) and provides an excellent opportunity for planners and engineers alike to learn more about this new analytical method and how it has been implemented by the states of Georgia and Florida.

Learning Objectives:

  • Describe the Safe System-Based Framework for Intersections;
  • Recall the key concepts and methodological requirements of this method;
  • Understand where and how this method has been implemented by Georgia and Florida.
