system provides traffic counting information
as well, traffic flow can be effectively
managed both automatically and by real-
time operators in the monitoring room.
Violation management
If a vehicle breaks the traffic rule, the video
content analysis module automatically
detects it with high precision. It marks
five corresponding images that show the
offending vehicle and creates a violation
package that contains the automatically
cropped license plates as well. These
packages are then sent to the Violation
Management Center via WiMAX wireless
communication installed by Infinet Wireless.
This unique architecture also allows
optimising the bandwidths from each of the
traffic junctions to the central control rooms.
This is performed by pulling only the required
data pixels from the video images by using
JPEG2000 visually lossless compression. At
the same time SensorTec archives over one
month of videos on-site itself.
The violation packages with the processed
camera images arrive at the Violation
Management Center via high-speed wireless
network provided by Infinet Wireless. The
Violation Management Server manages
the violation packages, stores them in a
centralised database and it downloads

several images of the offending vehicle to
a centralised image container. It maintains
communication with the Automatic Number
Plate Recognition Server, the Government
database and transmits violation packages
to the violation management clients.
Control room
In Cairo, two monitoring centres operate
within the SensorTec System in two different
locations. Both centres are designed for real
time operation, but inside one of them the
Violation Management Centre has been set
as well. They are able to fully control the IP
video system in real time. Basically, one of
them is intended to concentrate only on city
surveillance tasks, and the purpose of the
other is to fulfil traffic surveillance. There is
5 GB, high-speed, wireless communication
line between the two monitoring centres,
provided by Infinet.
A huge video-wall and a couple of
workplaces serves the operators for real-time
monitoring at each control rooms. They use
the industry’s most reliable and user-friendly
VMS, the Control Center software. The
programme provides functionality to access
the most detailed live videos of the situation
and watch archived footage.
In the Violation Management Control Room,
there are workplaces for the operators and
for the supervisor to confirm the processed
traffic violations. The police officers use the
Violation Management Clients to confirm
automatically detected violations. The
user-friendly design of this software ensures
a daily 10,000 citations throughput for
each workstation. This high performance is
essential, because on the streets of Cairo
every camera could detect thousands of
violations every day.
The confirmed violation report can be
automatically exported for the government
summon issuing system. This export contains
every essential information of the violation,
such as pictures about the violation, car
data, date and time, and violation types. The
format of the export is customer dependent,
by default it is an XML file. Additionally, the
SensorTec Traffic system can generate a
complete police report. This PDF file contains
images and violation details, according to
the user defined format.
SensorTec System is maintaining the security
in Cairo’s everyday traffic by detecting and
recording several types of traffic violations
and providing irrefutable evidence for local
authorities. As drivers know their offending
actions could be captured, they will comply
with traffic rules. Such a well-functioning
system helps to improve traffic, increased
throughput of roads, reduced traffic jams,
and lowering of transport time and costs. n
