SCATS and the Environment Study: Definitive Results

This paper presents the finalising, definitive results of a study called the 'SCATS and the environment (SatE) study'. The SatE study was designed to reveal the transport, environmental and economic value that the SCATS traffic management system delivers to the road stakeholders of the Australian state of New South Wales. The performance of 21 SCATS-controlled intersections was assessed across 24 hours on a key, strategic route in Sydney, Australia. SCATS adaptive and optimising traffic control operation was compared to a realistic alternative operation, which represents a reactive, semi-adaptive, fixed time system. The final results demonstrate that SCATS delivers significant value to road network stakeholders. Indicative reductions of 28% travel time, 25% stops, and 15% CO2, 13% NOx and 15% PM10-emissions of vehicles were demonstrated. Together, these reductions were interpreted to provide an indicative, total opportunity cost savings of AUD $143,592 or 27% of the total cost, at 2009 values, for the studied 24 hours across the corridor. The authors defend the results by articulating the robustness of the calibration and validation. The paper is useful to those wanting a defensible reference that indicates the contributions delivered by a SCATS installation at a corridor level.
