tech transfer summary Evaluating Red Light Running Programs in Iowa

As communities across the United States attempt to address red light running (RLR), a number of them have implemented RLR camera-enforcement programs. Since 2004, three Iowa communities—Davenport, Council Bluffs, and Clive—have implemented RLR camera-enforcement programs. The objective of this research was to evaluate the effectiveness of RLR cameras in these three Iowa communities. A reduction in crashes was evaluated for Council Bluffs and Davenport, and a reduction in the number of RLR violations was evaluated for Clive.
