Sydney Coordinated Adaptive Traffic System
From Wikipedia, the free encyclopedia
The Sydney Coordinated Adaptive Traffic System, abbreviated SCATS, is an intelligent transportation system developed in Sydney, Australia by the Roads and Traffic Authority. It is also used in New Zealand, Hong Kong, Tehran, Dublin, Rzeszów and soon in part of Metro Atlanta,[1] among several other places. The system is called Canberra Automated Traffic Signal System (CATSS) in Canberra. In total, about 23,000 intersections in over 100 countries use the system. In Australia, the majority of signalised intersections are SCATS operated (around 11,000).
The system uses traffic cameras or induction loops installed within the road pavement to count vehicles at each intersection, and adapts the timing of traffic signals in the network through a centralised datacentre. Detailed signal diagnostics are also passed to the datacentre, with the ability to notify staff when a traffic light has a bulb blown out.
A SCATS system is able to operate over PAPL or ADSL network connections to each intersection. The system is mainly used with the TYCO Traffic Controllers but other controllers can be interfaced with ad-on modules.
