  • Abstract:
    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. In addition to providing a test of the methodology, this study would also measure whether there were changes in driver satisfaction with roadway quality as a result of the deployment of the adaptive signal system control. Cobb County had recently completed a retiming of the corridor, so the current study would provide insights on whether there is value added – from the customer’s perspective – when one moves from an optimized coordinated signal system control to an adaptive signal system control. In order to isolate external effects that might impact driver satisfaction ratings but which are unrelated to the traffic signal improvements, a “control” panel was also used, whereby a panel of drivers was surveyed on a comparable corridor where there was no signal system upgrade. The expectation was that drivers on Paces Ferry Road (the treatment route) would be more satisfied with the roadway quality after the system was deployed compared to pre-deployment, whereas there would be no change in satisfaction among the Spring Road drivers (the control route). Cobb County also assessed the performance of the new signal system through an independent evaluation conducted by the Georgia Institute of Technology. Using floating cars studies, the Georgia Institute of Technology collected objective measures for travel time, speed, and delay both before and after the signal system upgrade.
