Aitken Redesign

From 2010 – 2018, the city of Garden Grove was home to nearly 4,000 intersection related motor vehicle crashes.  These crashes resulted in over 2,500 injuries and 18 deaths.

Where are Garden Grove motorists at the highest risk of collision and injury?

As part of a larger study, Aitken Aitken and Cohn identified the 25 most dangerous intersections in Garden Grove, CA based on collision and injury volume.

* Intersections are ranked according to their Crash Risk Index (CRI) score.  CRI is a composite score that takes the crash count and the volume and severity of injuries into account.
