Is there any reliable statistical method to evaluate safety effectiveness of countermeasures for rare crashes (like 1 crash/year/location)?

We aim to evaluate the safety effectiveness of already implemented countermeasures for wrong-way driving (which is pretty rare) at several locations. The before-after data is also available.
