The Federal Highway Administration (FHWA) established the Development of Crash Modification Factors (DCMF) Program in 2012 to address highway safety researchers' need to evaluate new and innovative safety strategies (improvements) using reliable, quantitative estimates of the effectiveness of these strategies in reducing crashes. Forty-one State departments of transportation provided technical feedback on safety improvements for the DCMF Program and implemented new safety improvements to facilitate evaluations. These States are members of the Evaluations of Low-Cost Safety Improvements Pooled Fund Study (ELCSI–PFS), which functions under the DCMF Program.

This project evaluated the safety effectiveness of adaptive signal control technologies (ASCTs) at urban intersections. The ELCSI–PFS Technical Advisory Committee determined that such an evaluation was among its high-priority activities.
