Safe System Approach

Imagine a world where no one dies from vehicle crashes

People make mistakes

A safe transportation system recognizes this reality. Engineers should create roads and vehicles that anticipate human mistakes and prevent them from leading to death or serious injury.

Humans are fragile

Our bodies can only withstand so much force in a crash. The system must be designed to protect us. Features that slow down traffic, separate different types of road users, and add layers of protection all help to reduce the risk of severe outcomes when crashes occur.
