Bridges Safety and Security


Bridges are key transportation infrastructures; they are also vulnerable infrastructures: any incident on a bridge is likely to have major consequences in terms of Safety and Security.

Time is of the essence when detecting and responding to an incident in order to prevent secondary accidents and congestions.

This is the reason why Bridges Traffic Management Centers have turned to Video-based Automatic Incident Detection solutions to assist Traffic Operators to efficiently monitor traffic and quickly respond to incidents.



Why video detection is the ideal tool for bridges Safety and Security

No other sensor provides such a fast, reliable and exhaustive detection of events.

It is fast.

It provides Traffic Operators with alarms (audible and/or visual) immediately after an incident occurs (within seconds), even before the consequences of this incident can be noticed by a traditional surveillance system.
It enables users to be warned in good time and reduces the risk of multiple accidents and congestions.

Any traffic disruption is instantly reported to the traffic managers at Control Centres with a view to optimizing the reaction time.
It is reliable.

The maturity of video incident detection technology now allows traffic operators to expect high performance levels when it comes to detecting the right event.
It assists the operator in making the right decision.
Real time incident validation tools are provided to operators such as instantly available pre and post incident video recordings.

How does a Video Detection System work?

Existing video signals from the bridge CCTV system (analog or digitally encoded) are fed into a Video Detection Unit.

The Video Detection Unit runs a Detection Algorithm. This algorithm is based on tracking techniques and trajectory analysis and detects stopped vehicles within the field of view of the camera.

All Video Detection Units are linked to a Supervisor that receives and dispatches the alarms to Workstations and/or ATMS / SCADA systems. Operators are then, instantly provided with the location of the incident, its type, the live video image and the recording of the seconds preceding the incident.

All these elements combined together allow for a fast and efficient response to incidents.

Can it be installed at any bridge?

Citilog video detection solutions have been designed to fit into an existing CCTV architecture, be it an analog transmission or an IP encoded CCTV network. Video Detection Units are located wherever the video signals are available (in the field, in a hub or at the Traffic Control Centre). The systems architecture is flexible and Citilog offers a wide range of communications solutions.

Citilog's extensive experience in bridge Management, Security and Safety have already led us to successfully apply our video incident detection algorithms to short, heavy traffic urban bridges, high speed motorway viaducts and long cross river bridges where cameras are often shaken by high winds.

Why is Citilog recognized as the World Leader for Automatic Incident Detection?

From its earliest development 20 year ago to its most recent enhancements, Citilog Video Image Processing algorithms have been focused on incident detection and the transportation industry. Because this algorithm is not based on Traffic Data variation or Loop Emulation but on true Vehicle Tracking, our systems are far more accurate and reliable.

Citilog is recognised as the leader in Automatic Incident Detection because Vehicle Tracking techniques have proved their superiority in both detecting the right event but also in presenting Traffic Operators information that they can rely on.

Our Video Incident Detection Systems are field-proven and have been successfully deployed worldwide to enhance Safety and Security on various types of road infrastructures: highways, expressways, bridges and tunnels.
