The Traffic Operation Centre (TOC) monitors and manages traffic on the road network 24 hours per day, including the operation of all traffic signals, variable message signs and traffic monitoring cameras. TOC facilitates the timely response to traffic related incidents on the arterial road network to maintain traffic flow. The centre also provides priority at traffic signals for emergency services (police, ambulance, fire) during high priority escorts and modifies traffic signal operation locator for special events such as parades, football matches, or concerts.
When the original wall became uneconomic to maintain, the decision was made to upgrade both the physical display and also the video signal management. Since most of the cameras are now providing a digital signal back to the TOC, and the future plan is to have all digital camera feeds, signal integrity demanded the upgrade include a complete digital signal path to the displays.
Concept AV worked closely with the key stakeholders to design a system which meets the current requirements, and provides maximum upgrade flexibility for the future. The time frame was also a key consideration, with the existing wall needing to be removed, and then the new wall constructed and commissioned.
Factory Acceptance Testing in Concept AV’s West Perth facilities was instrumental to ensuring the new infrastructure could be seamlessly integrated with the TOC systems with the shortest practical downtime.The system installed incorporates a General Traffic Video Wall made up of an array of 2 high by 6 wide rear projection 67” 1024x768 units, and a Graham Farmer Freeway Tunnel dedicated Video Wall, made of an array of 2 high and 3 wide rear projection units. Both walls have been designed with the ability to expand both in height and width.
Concept AV provided a complete design, installation, commissioning, testing and maintenance service, including all facets from structural design to acoustic considerations, and including signal distribution and management, sight-line analysis, ventilation, lighting, and power requirements.
