Tomorrow’s traffic monitoring
technology today
Since in the course of a | Need to know
working day various members
of staff would access the wall,
it also needed to be possible
to partition the sources of the
media wall as required. In
addition, each display needed to
have a 16:9-width-to-height ratio
and full-HD-resolution so that
the smallest detail of the camera
shots could be displayed.
Ticking all boxes
The solution meeting the criteria
and that the SSB ultimately
opted for is a 8.76m wide and
1.64m high wall displaying 48
live camera images making it
possible to monitor the whole
public transport network
offering swift, coordinated
responses to any disruption
of operations or dangerous
situations that may arise.

Consisting of 12 x 67in LEDback
projection cubes, the new
wall supplies the traffic control
center employees with a
complete picture of the network.
The SSB-personnel have
continuous access to live images
from all routes of the network
via the wall, which is in
operation for 24 hours a
day, seven days a week.
The rear-projection
technology of the display
cubes prevents burning of static
image content on the screens,
guaranteeing high contrast
values and no loss of color
quality in the illumination.
The flicker-free image
presentation on the displays
has no rainbow effects and –
even in 24/7-operation – is
less tiring on the eyes for
SSB-employees.
Over the last decade the
traffic manager role has
significantly changed.
Due to the ‘IP-ification’ that has
become ubiquitous, in regard to
higher resolution cameras, track
and trace maps, signs, other IoT
devices and even social media.
It all means that an abundance
of data is now available for the
modern traffic manager.
However, it has also become
more complex for them to cope
with all this extra information.
What is required for the modern
traffic control center is a high
performance visualization
solution that can show the
correct information at the
correct time and allow for
interactions with it.
The expectation is for a real
time-responsive video wall
independent of the complexity
that lies behind the technology.
Stuttgart’s situation
The sixth largest city in
Germany, Stuttgart has a
thriving tram and bus network
managed by the Stuttgart
Straßenbahnen AG (SSB).
Responsible for around 450
vehicles that travel on more
than 9,000km of routes, SSB was
keen to invest in a modern video
wall that could support them in
meeting the challenge of
transporting 500,000 travelers
on their network every day in
a safe and timely manner.
Having commissioned
consultants to help in deciding
the direction to go, the SSB had
a list of demands for potential
technology suppliers.
Among them, the criteria
included that the new video
wall should have a long
lifespan. Another was that the
bezels between the active image
area of the individual displays
should be thinner than one
millimetre, so that content could
be spread over several screens.
