SCATS is a leading adaptive area traffic control system which uses roadside and junction sensors to determine appropriate traffic signal settings to improve traffic control. Its comprehensive features include fault monitoring, maintenance scheduling, traffic data collection and analysis, emergency vehicle progression, and public transport tracking. It can manage groups of junctions centrally, but its roadside equipment also applies important tactical control, providing cities with a traffic control system flexible enough to be adapted to their own requirements. The Roads and Traffic Authority (RTA) of NSW, Australia, continues to enhance SCATS to meet the requirements for its use in Sydney and the demands of other SCATS users in Asia and the USA. The RTA can test new features and improvements on Sydney's road network before they are released to other users. AWA Traffic Systems, the developer of SCATS, has been working with the RTA for over 30 years. The Automatic Network Travel Time System (ANTTS) continually collects travel time data from vehicles using their normal routes, and generates management reports about traffic. ANTTS is also used on the Sydney Airport Express Bus Service. In the USA, the Integrated Corridor Traffic Management System (ICTM) manages traffic moving between freeways and arterial roads.
