Automatic incident detection for the Calgary Airport Trail Tunnel, Canada

Video-based automatic incident detection technology from FLIR has been installed in numerous tunnels around the world. In the Calgary Airport Trail Tunnel in Canada, FLIR’s video analytics boards are combined with both visual cameras and FLIR thermal imaging cameras. For both types of cameras, FLIR delivers accurate detection of a wide range of incidents, including pedestrians, fallen objects and inverse direction. The tunnel runs under the airport runway. It is 620 metres, 36 metres wide and has a vehicle clearance of 5.3 metres. The Airport Trail tunnel opened to traffic in May 2014 and connects the airport to other important areas of the city. The tunnel includes 8 FLIR FC-Series ITS cameras, which produce accurate traffic images on which the smallest detail can be seen.
