Sample Performance Measure

In this sample performance measure diagram, there are five levels of performance and their definitions, as follows:

1 – Very Poor. Work zone crash rate more than 30% higher than pre-construction crash rate.

2 – Poor. Work zone crash rate 30% higher than pre-construction crash rate.

3 – Fair. Work zone crash rate 20% higher than pre-construction crash rate.

4 – Good. Work zone crash rate equal to pre-construction crash rate.

5 – Excellent. Work zone crash rate 20% less than pre-construction crash rate.

An arrow indicates that the performance goal (or the "passing" score) is at level 4 – Good.
