NICTA is developing advanced sensing and surveillance technologies capable of providing rich information about traffic states to a new breed of smarter traffic control applications.
The major areas of research include object feature extraction, invariant pattern recognition and multi-sensor data fusion in order to obtain accurate, real-time information about individual vehicles and groups of vehicles and traffic states to better inform real-time traffic control decisions.
Accurate traffic flow measurement and vehicle classification together with stopped vehicle detection and the identification of traffic incidents and anomalies will offer a finer level of control to adaptive traffic control systems and provide for more rapid response to traffic incidents.
Extensive real-time test beds established on the streets of Sydney support the analysis and semantic level understanding of traffic at intersections and on motorways. In seeking solutions which afford low-cost installation and maintenance, the project is developing solutions which can make effective use of constrained position/angle cameras mounted on existing traffic signals under a range of weather and lighting conditions and the presence of heavy shadow, occlusion and congestion.
Reliable, low cost vehicle tracking, queue length estimation and vehicle classification at metropolitan and urban intersections and on motorways will provide valuable additional information enabling advanced traffic management and control systems to ease congestion, reduce variability in travel times and improve intersection safety.
Truly intelligent vision systems for traffic monitoring, remove the burden on human operatorís to detect and analyse traffic incidents and increas etheir capacity for higher-value tasks such as responding to the event itself.
NICTA sensors will be mounted at traffic signal height for ease of installation and maintenance and be effective in a range of weather and lighting conditions. Using data fusion techniques and enjoying a close coupling with the traffic modelling and control systems, traffic analysis will be impervious to the impact of vehicle occlusion which might otherwise diminsh the effectiveness of street-level video sensing.
