Implementing a Safe System approach involves providing multiple layers of protection to reduce the probability of fatal and serious injury crashes. The approach is guided by six overarching principles (Death and Serious Injuries are Unacceptable; Humans Make Mistakes; Humans are Vulnerable; Responsibility is Shared; Safety is Proactive; Redundancy is Crucial) and supported by five complementary Safe System Elements (Safer People; Safer Roads; Safer Vehicles; Safer Speeds; and Post-Crash Care).

This training will focus on the Safer Roads and Safer Speeds elements by introducing a Safe System Solutions Hierarchy that characterizes engineering and infrastructure-based countermeasures and strategies relative to their alignment with the goal of eliminating fatalities and serious injuries. The draft hierarchy is under development by the Federal Highway Administration to assist transportation agencies with implementation of the Safe System Approach. The hierarchy is intended to provide transportation practitioners with a new lens to consider kinetic energy management and how Safe System solutions can be implemented through example applications and case studies.

Learn how this hierarchy can aid in decision-making for street and road improvements that better accommodate for human mistakes and keep crash impacts on the human body within survivable levels.

TARGET AUDIENCE: All roadway transportation professionals
