A Study on Integrated SCATS Intersection and Ramp Metering Control

The Roads and Maritime Services agency, formerly the Roads and Traffic Authority of New South Wales, is initiating a process to upgrade the active management of motorway within the metropolitan area of Sydney, Australia. One of the objectives of this process is to provide an integrated strategy across the road network that includes arterial roads and motorways. This objective require the integration of dynamic traffic management tools such as adaptive signal control, ramp metering and lane use management across the network. This paper presents a first step towards this integration objective. It demonstrates some of the existing SCATS integration capabilities. It demonstrates this via a study comparing two example scenarios: one providing a non-integrated solution and another with an integrated solution. The study uses software-in-the-loop simulation by means of SCATSIM. SCATSIM is a software suite that allows SCATS to be linked to traffic microsimulation which enables the full SCATS functionality to be applied and analyzed with a microsimulation model. The study uses a microsimulation model with a ramp metered motorway segment and a signalized arterial road. The results demonstrate the traffic performance value that SCATS integrated control of signalized intersection and ramp metering sites provides compared to a non-integrated system.
