SAFETY BENEFITS:

10%
Reduction in injury and fatal crashes

15%
Reduction in nighttime crashes

This systemic approach to intersection safety involves deploying a group of multiple low-cost countermeasures, such as enhanced signing and pavement markings, at a large number of stopcontrolled intersections within a jurisdiction. It is designed to increase driver awareness and recognition of the intersections and potential conflicts.

Average Benefit-Cost Ratio: 12:1

The systemic approach to safety has three components: (1) analyze systemwide data to identify a problem, (2) look for similar risk factors present in severe crashes, and (3) deploy on a large scale low-cost countermeasures that address the risk factors contributing to crashes.

The low-cost countermeasures for stop-controlled intersections generally consist of the following treatments:

On the Through Approach
