STREAMS Integrated Intelligent Transport System is an enterprise traffic management system designed to operate in the Microsoft Windows environment. Like most traffic management systems, STREAMS is an array of institutional, human, hardware, and software components designed to monitor, control, and manage traffic on streets and highways. Advanced traffic management systems come under the banner of ITS (intelligent transport systems). ITS is an umbrella term referring to the application of information and communications technology to transport operations in order to reduce operating costs, improve safety and maximise the capacity of existing infrastructure. STREAMS provides traffic signal management, incident management, motorway management, vehicle priority, traveller information and parking guidance within a single integrated system. STREAMS is developed by (Transmax ). == History == In 1969, the (Department of Main Roads (Queensland) ) installed the first Intelligent Transport System in Australia (located at Surfers Paradise). This included 30 signalised intersections featuring centralised control and traffic responsive capabilities. In 1985, a second generation traffic management system was installed in Cairns, Australia. This was known as the TRAC System, or Traffic Responsive Adaptive Control System. Progressive installation of the TRAC system followed at several more sites around Queensland including the capital city, Brisbane. In 1988, a traffic management system was installed for the South East Freeway in Brisbane, Australia. The features included were ramp metering and graphical displays of traffic conditions. It also provided automatic incident detection. In 1992, a new integrated intelligent transport system development was commenced. The objectives were to lower ongoing costs while providing increased performance and opportunity for future ITS applications. The resultant system was STREAMS. In 2002, the division of Department of Main Roads (Queensland) responsible for continuing development of STREAMS was privatised to form (Transmax ). The company remains 100% owned by the (Queensland Government Department of Transport and Main Roads ). In April 2007, Transmax in partnership with VicRoads implemented a coordinated ramp metering trial in Melbourne, Victoria on a 15 km section of the Monash Freeway. Later that year, in December, VicRoads installed STREAMS to manage another six ramps. These developments were part of a much larger M1 Upgrade Project that continued over the next three years, eventually winning the 2010 National ITS Australia Award. The project to upgrade the 75-kilometre M1 Freeway, increasing the capacity and safety of the Monash Freeway, the CityLink Tollway (Southern Link) and the West Gate Freeway utilising STREAMS as the Integrated Control System. New versions of STREAMS are regularly released as state-of-the-art functionality is developed. The name STREAMS was derived via the association of managing multiple modes or "streams" of traffic (e.g. public transport, private cars, pedestrians, bicycles, and commercial vehicles) as well as the concept of "streams" of data which are inherent in any distributed computing system. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「STREAMS Integrated Intelligent Transport System」の詳細全文を読む スポンサード リンク
