This paper will discuss how SCATS (Sydney Co-ordinated Adaptive Traffic System), used widely throughout New Zealand, can be used to manage the sudden change in traffic demand resulting from incidents on the transport network. SCATS is an adaptive traffic signal control system that uses real time traffic information (loop detectors) to adjust phase splits, cycle times and offsets to optimise a signalised traffic network, resulting in reduced delays to motorists. This paper will focus on how SCATS can be modified to detect and respond to incidents. Various tools are available within SCATS to handle unique traffic situations, such as those resulting from incidents. These include action plans, variation routines, using the unusual congestion monitor and the ITS port. The benefits of using these tools will be shown using a an S-Paramics traffic model linked to SCATS with FUSE. This allows various incidents to be modelled in a microsimulation model with the signals operating under SCATS control. The model used includes the Northern Motorway on Auckland’s North Shore with various diversion routes off of the motorway. Various incidents will be modelled on and off of the motorway, showing traffic diversions on the arterial network. This case study will show how travel time on diversion routes used during incidents, can be decreased by using the SCATS as an incident management tool. This paper will discuss incident management strategies, the various SCATS tools available to handle incident scenarios, and present the benefits of these SCATS tools using a case study.
