This report presents findings from a customer satisfaction study conducted in Cobb County, Georgia. The primary hypothesis of this study is that it is possible to develop customer satisfaction measures that are a reliable determinant of roadway quality. A signal system upgrade in Cobb County, Georgia offered the opportunity to test this hypothesis. The Cobb County Department of Transportation planned to instrument 15 signalized intersections on Paces Ferry Road with the Sydney Coordinated Adaptive System (SCATS). In order to test its proposed methodology for measuring customer satisfaction with roadway quality, the Volpe National Transportation Systems Center (Volpe Center) conducted a before-and-after study of drivers on the Cobb County urban arterial treated with the adaptive signal system control.
