To cope with the rapid growth in traffic in Dublin, Eire, Dublin City Council has introduced an extensive CCTV surveillance system for traffic monitoring. AMG Systems were asked to link CCTV, traffic signal controllers and other traffic management equipment to the control room to ensure that traffic keeps moving, particularly at rush hour. AMG Systems' Guardian 2800 multi-channel video transmission system was first used on the M50 motorway. This is a fibre-optic ring configuration designed to transmit live, full-bandwidth video images from each individual camera on the motorway to the control room. The Guardian-Lite 2700 transmission equipment was used on the M1 motorway and N11 dual carriageway. The 2700 series can be configured in dual ring mode or as a spur. The city traffic conditions are now monitored round the clock in the DCC Traffic Control Centre. Each of nearly 100 cameras is linked directly to the control room. The video signal is not compressed. Traffic conditions on two thirds of the city's junctions are managed by the SCATS traffic control system. This balances priorities between quality bus corridors, LUAS tram lines, general traffic, pedestrians and cyclists. The transmission network integrates the Sydney Coordinated Adaptive Traffic System (SCATS) traffic control system and the CCTV surveillance system.
