of transportation infrastructures rely heavily on the use of CCTV - and
particularly Pan-Tilt-Zoom (PTZ)- cameras. But as expansion of CCTV
camera use in the field of traffic and roadway monitoring continues,
CCTV systems are beginning to meet with limitations: too many cameras,
too many monitors, TMC not manned 24/7...
In other words, most of the information provided by CCTV cameras is
under-used or not used at all because Traffic Operators are not aware
of it in real-time.
However, 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 Traffic Management Centers have
turned to Advanced Video Surveillance solutions to assist Traffic
Operators to efficiently monitor traffic and quickly respond to
|Why Advanced Video Surveillance is a key tool for to highway Safety?|
Video Surveillance 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.
it requires not setup or calibration, Advanced Video Surveillance fits
perfectly into any CCTV system: no need for additional or new cameras,
no need to use preset positions.
How does an Advanced Video Surveillance system work?
video signals from the CCTV system (analog or digitally encoded) are
fed into a Video Detection Unit. The Video Detection Unit runs a
This algorithm is based on tracking techniques
and trajectory analysis and detects stopped vehicles within the field
of view of the camera. It is a self-learning algorithm that does not
require any setup or configuration: it automatically learns the traffic.
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.
Can it be installed at any Traffic Management Center?
Advanced Video Surveillance 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
The systems architecture is flexible and Citilog offers a wide range of communications solutions.
extensive experience in Highway Management, Security and Safety has
already led us to successfully apply our solutions to Expressways,
Highways and Bridges. Based on this field experience Citilog has
developed specific algorithms to control camera vibrations, thus
ensuring more reliable and accurate detection on Highways or Bridges
cameras often shaken by high winds.
All these elements combined together allow for a fast and efficient response to incidents.
Why is Citilog recognized as the World Leader for Advanced Video Surveillance?
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.
Citilog is the only
system that has a self-learning algorithm able to report accurately and
reliably incidents and that can be easily integrated in any CCTV system.
is recognised as the leader in Video Incident Detection because our
systems present Traffic Operators information that they can rely on.
Advanced Video Surveillance Systems are field-proven and have been
successfully deployed worldwide to enhance Safety and Security on
various types of road infrastructures: Highways, Expressways, Bridges
