When conducting a Safe System Assessment, one key task is to predict potential crashes and quantify their exposure, likelihood, and severity. This is done using the Safe System Assessment Matrix, which includes separate columns for run-off-road crashes and intersection crashes.

But what happens when a predicted run-off-road crash occurs at an intersection?

The answer: it increases the run-off-road score, but not the intersection score.

Why? Because intersection crashes are specifically reserved for collisions between vehicles, not vehicles running off the road.

While the Safe System Assessment is designed to be a broad evaluation tool, understanding these nuances is crucial for accurate scoring.

Our Safe System Assessment training course dives deeper into these subtleties and more. Plus, we’ve developed a series of fact sheets to support practitioners in applying the assessment process effectively. Check them out here.
