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.

maturity of video incident detection technology now allows traffic

the right event.
It assists the operator in making the right decision.

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.
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.
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
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.
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
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.
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.
