“Vision Zero“ –
➲ A new way of viewing traffic safety
Gaining Popularity
Germany is tackling the problem of fatalities and injuries
in street traffic with a new philosophy. “Vision Zero” is
more than a program. It can, indeed, be compared to
a humanistic approach. The message: society must
cease simply accepting the number of victims of traffic
accidents.
The previous success of traffic safety work is above
question. However, the statistics are not acceptable: in
2007 almost 5,000 persons died in traffic accidents, more
than 440,000 were injured, in many cases severely. In
the same way in which the organizers of Formula 1 races
reacted to fatal accidents with drastic modifications,
new measures must help to increase safety in everyday
traffic. Many associations, including the German Traffic
Safety Council, support “Vision Zero”.
The new approach changes the way in which traffic is
viewed. The system must be based on the fallibility and
not the perfection of human beings. Thus it follows that
human beings become the given constant to which the
traffic system must be adapted! RTB products fit
perfectly in “Vision Zero” because they have been
proven to increase safety in street traffic and can be
adapted to individual situations.
Soon such situations should disappear.
This is the goal of “Vision Zero”.

net.1
➲ net.1 creates attractive cost saving potential
If a central module controls the signal facility for blind
pedestrians by way of a field bus then it is using net.1.
With this innovative system RTB clearly reduces costs,
especially when retrofitting existing traffic light facilities.
From now on, one can produce the wide variety of
signals using only a single cable wire to the pole.

net.1
Intelligent
Cable

Connection
The net.1 central module is installed in the signal control
device. It consists of at least two individual circuit
boards with European card format:
• The communication card is the communication center
of the net.1 bus in the exterior facility.
• One or more interface cards each provide 6 connector
groups for the push button and the acoustic signal
transmitter.
Pluggable multipoint socket connectors with crimp
technology in accordance with DIN 41612 serve as maintenance
friendly contacts and comply with the established
technical standards. Both cards must be integrated
together in 3HE installation points in the control device
(Further function description in the Information Box).
The net.1 pole module is the bus participator on the
pole for the conversion of the net.1 signal into inputs
and outputs for the push button and the acoustic signal
transmitter. It consists of an add-on card, which can be
ordered as an option for the signal transmitter for blind
pedestrians. It is installed in the transmitter by the
manufacturer. The connectors for the compatible push
button which no longer need to be connected with the
ground cables are located on the net.1 pole module.
Using this one-of-a-kind technology RTB can clearly reduce
the costs for retrofitting existing traffic light facilities.

Function description
of the net.1 central module
● In terms of hardware, the interface card mirrors the
contacts of the signalization for blind pedestrians and
the push button from the pole in the control device.
Without net.1 these would have to be connected to
the exterior facility via ground cables. Instead of
ground cables, the net.1 communication handles the
task. In terms of hardware, this is a switch-cabling
within the device without a galvanic connection to
the exterior facility. The interface card modulates the
signals into special digital form and communicates
with the communication card via CAN bus. From
there the data are conveyed to the exterior facility via
the shared net.1 wire.
● The communication card carries out two tasks. It
serves as the communication center for net.1 devices
by providing for user friendly allocation to the signal
group when turned on and by serving as the gateway
between interface cards and exterior facility during
operation. Furthermore, it is a blocking filter between
the control device and the net.1 field device circuit.
Thus, the net.1 wire in the ground cable net is decoupled
from all other users in the lamp power circuit.

Axe Recog
➲ Extended functionality now available with the TOPO.plus
Now RTB is revealing the next secret for classifying
vehicles. The new product, TOPO.plus, can measure not
only the speed, length and the acoustic characteristics
of vehicles. It also makes it possible to reliably recognize
axles. From now on a differentiation according to 8 + 1
classes and other differentiations are possible – a
dimension that until now was out of reach.
An optimal control of traffic flow is very important
for a number of reasons. One can avoid traffic jams,
reduce emissions and immissions and improve traffic
safety (Key word: “Vision Zero”). The most important
prerequisite is, however, an absolutely precise
analysis of the existing traffic situations. Here TOPO.plus
offers exceptional possibilities. It can, irregardless of
class, identify vehicles with a detection rate of up to
99 %.
According to the TDCWS (Technical Delivery Conditions
for Way Stations) of the Federal Institute for Traffic
Matters, the exact recognition of individual vehicle
axles makes it possible to draw conclusions about the
type of vehicle. TOPO.plus differentiates extremely well
here: for example between motorcycles and small automobiles
(such as the Smart) or between trucks (with and
without trailers) and busses. A differentiation according
to 8 + 1 vehicle classes can be done with almost no
mistakes. This also applies to further differentiations
based on characteristics such as placement of axles and
position of motors.

nition
Important traffic data can be transmitted either by an
integrated Bluetooth interface or via a GSM connection.
The extremely user friendly internet application DD.web
then provides for a rapid interpretation exact to the last
detail – this is the perfect basis for measurement to
control traffic flow.
With TOPO.plus RTB offers communities a new
possibility for planning and managing street traffic.
In this manner problems of residents, for example
with truck traffic in the inner city or with traffic at
night near hospitals, can be solved on an individual
basis.

Trade Meeting
im October
In the Fall we’re off to Düsseldorf: From October 8
through 10, 2008, experts for street traffic technology
will meet at the traditional German Street and Traffic
Congress. In the capital of North Rhine Westphalia RTB
will present current innovations, in particular net.1
(page 4/5) and TOPO.plus (page 6/7). The opening times:
Wednesday (October 8) 8.30 a.m. – 6.30 p.m., Thursday
(October 9) 8.00 a.m. – 6.15 p.m. and Friday (October 10)
in Bavarian Style
Regional differences can be so pleasant! In front of the
Brewery on Tegern Lake one still uses the traditional way
of reducing speed. This dialogue may work well at this
location. At other locations, RTB’s modern solutions,
such as the Dialogue-Display, certainly offer more
advantages.
8.00 a.m. – 13.30 p.m.
Admission is free of charge.
Tiefensee
and the Dialogue-Display
Federal Traffic Minister Wolfgang Tiefensee presented
himself at the Annual Main Meeting of the German
Traffic Watch in Potsdam as a friend of modern solutions
for more safety in street traffic. This top politician also
made positive comments about RTB’s Dialogue-Display.
