VDG Sense records and protects the Yavuz Sultan Selim Bridge in Istanbul

The Bosphorus is a narrow, natural strait and an internationally important waterway in north-west Turkey. It forms part of the continental boundary between Europe and Asia, and separates Asian Turkey from European Turkey. The Yavuz Sultan Selim Bridge is a motor vehicle and railway bridge over the Bosphorus in Istanbul, to the north of two older suspension bridges. At 322 metres, the bridge is the tallest suspension bridge in the world.

Monitoring the bridge, which is part of the city’s new ring road, which also has two tunnels, is essential. The bridge consists of a four-lane motorway in both directions and two high-speed railway tracks, and is used in each direction by approximately 135,000 vehicles per day. VDG Sense records events via AID (Automatic Incident Detection) video registration. In the event of abnormal circumstances, such as a pedestrian on the road or a car driving against the direction of traffic, a ‘macro’ is generated. These incidents are identified in the central control room via the VDG Sense application and the operator is informed proactively, with the help of an audible alarm and camera pop-ups, so that he can react quickly and alert the emergency services, if necessary. VDG Sense is also used for retrieving and reviewing videos of incidents.
