Editorial<br />
Dear Readers,<br />
One must admit that in our field we deal with rather dry<br />
material which has a complexity that is rarely recognized<br />
by those outside the field. Everyone is familiar with<br />
traffic lights, commonly known as stoplights, but that’s<br />
about it.<br />
So when one of the leading business magazines in Germany<br />
such as impulse – The Businessman`s Magazine<br />
gets excited about a development in our field, this must<br />
be considered a giant step forward !<br />
The German Chamber of Industry and Trade (DIHK)<br />
and the magazine impulse, in the framework of the<br />
competition “Potential Innovation“, present awards to<br />
companies, which stand out with convincing innovation<br />
in the market place!<br />
We express our heartfelt congratulations for receiving<br />
this award to the company DTV-Verkehrsconsult <strong>GmbH</strong>,<br />
and in particular to Dr. Hartmut Ziegler and Dr. Thorsten<br />
Kathmann, who, along with their team are promoting<br />
nation-wide traffic monitoring in Germany (cf. the<br />
October issue of the magazine impulse).<br />
In order to put such ideas into practice one needs<br />
courageous persons and customers who are prepared to<br />
keep working on an idea and carry out such a project as<br />
nation-wide traffic monitoring. Special mention must be<br />
made here of the State of Baden-Württemberg which<br />
can be rightly proud of its presentation of this idea at the<br />
German <strong>Traffic</strong> <strong>Co</strong>nvention in Mannheim.<br />
We are also proud to contribute to this development<br />
with our classification devices.<br />
Once more our heartfelt congratulations to all involved!<br />

Along with the life-sized figures of children the Dialogue-Display<br />
is now contributing to the reduction of speeding.<br />
Innovative Safety<br />
Pilot project with the Dialogue-Display in the community of Hörden<br />
In order to increase safety at a frequently used<br />
pedestrian crosswalk, the community of Hörden<br />
initiated a pilot project using the Dialogue-<br />
Display.<br />
In Hörden pedestrians must use a crosswalk<br />
to reach a grade school, a general purpose<br />
building, athletic fields and other leisure time<br />
areas. School children are especially affected by<br />
this quite difficult situation in street traffic.<br />
Several years ago the community set up life-<br />
sized figures of children at this traffic junction,<br />
in order to warn car drivers and increase their<br />
attentiveness. However, last year a child was<br />
slightly injured at this intersection. The<br />
community`s request to have a traffic light installed<br />
was rejected by the county authorities.<br />
Therefore, the community took the initiative.<br />
For each direction of travel a Dialogue-Display<br />
has been installed, mainly to achieve observance<br />
of the speed limit of 30 km/h. When the facility<br />
went into operation one could immediately<br />
observe its effectiveness. A car driver who<br />
happened to pass by was promptly scolded<br />
with a red “Slow down”.<br />
After the first weeks of operation, the unanimous<br />
opinion of all those involved: The Dialogue-<br />
Display makes an important contribution to<br />
the safety of the weakest participants in<br />
traffic.<br />

<strong>Traffic</strong> <strong>Light</strong> <strong>Report</strong> No. 55<br />
The variable motif design makes multiple uses possible: Safety at a kindergarten and safety at an agency for senior citizens.<br />
An interview with the Mayor of Niestetal Andreas Siebert<br />
Niestetal is one of several communities which has decided to use Dialogue-Displays to<br />
make sensitive locations (e.g. in front of kindergartens and schools) safer. Certainly the<br />
recommendations of the German Insurance Federation (GDV) support this decision.<br />
Mayor Andreas Siebert explained his position to us in the following Interview.<br />
Mr. Siebert, what exactly was the reason for your intensive consideration of the topic of speed displays?<br />
We pay very special attention to traffic areas near kindergartens and schools. Of course, our Office for Public Order<br />
conducts sporadic speed checks in these streets and we ticket and fine some speeders for exceeding the limit. However,<br />
I think that the permanent installation of a Dialogue-Display has a significantly greater and longer lasting effect. One<br />
can influence the car driver in a positive manner with the words “Slow down” and “Thanks” which are displayed<br />
dependent on the speed of the passing vehicle.<br />
How did you learn about <strong>RTB</strong> and in particular about the Dialogue-Display?<br />
Once the decision to install Dialogue-Displays had been made, we searched the market place for manufacturers of<br />
such devices. The price and the flexibility for the optical design of the display were the decisive aspects for giving the<br />
contract to <strong>RTB</strong>. In the meantime there are more cities and communities which have chosen <strong>RTB</strong>.<br />
Why did you expressly choose the Dialogue-Display?<br />
Speed measurement facilities which covertly photograph drivers when the speed limit is exceeded and result in a<br />
warning ticket or a fine are frequently a lesson for car drivers. Experience shows, however, that this effect doesn’t last<br />
very long. This is different with the Dialogue-Displays, which are in operation 24 hours a day and react directly to the<br />
driving behavior of traffic participants. Studies by accident researchers have shown that the words ”Slow down” and
Successful Application<br />
Dialogue-Displays for more safety<br />
The community of Niestetal places special<br />
value on safety in street traffic in the vicinity of<br />
schools and kindergartens. The recently installed<br />
Dialogue-Displays should insure that<br />
car drivers adjust their speed according to<br />
the situation – especially at locations where extreme<br />
caution is necessary.<br />
What is special about the display signs is<br />
that the car driver is not only warned when<br />
exceeding the speed limit but also praised for<br />
observing the speed limit. With both phrases<br />
“Slow down” and “Thanks”, displayed in red and<br />
green respectively, the Display reacts directly<br />
to the driving behavior of the driver. Mayor<br />
Andreas Siebert states, “that accident re-<br />
searchers recommend this kind of display,<br />
because at some point in time simple traffic<br />
signs are disregarded. It has been proven that<br />
this loss of effectiveness with the passage of<br />
time is also true for signs that display only the<br />
current speed of the passing vehicle.”<br />
A total of seven Displays, some of which are<br />
powered by solar energy, are now installed at<br />
selected locations in Niestetal. Siebert: “We<br />
hope that traffic safety, especially for children,<br />
will be significantly increased by the Dialogue-<br />
Displays. The reaction of the public to the sign<br />
displays is, in any event, unanimously positive.”<br />
(Press release of the community of Niestetal, Text Bachmann)<br />
“Thanks” make a strong emotional impression on drivers. Due to the fact that the effectiveness does not diminish with<br />
the passage of time, the results with the Displays last significantly longer.<br />
Who was involved in the decision process in your community?<br />
One the one hand, of course, our street traffic authority, which determined potential locations and obtained various<br />
pro forma invoices. On the other hand the community board of trustees, which made the final decision.<br />
What criteria were used to select the locations?<br />
In the two sections of our town we have four communal kindergartens, two grade schools and one 1 - 13 school –<br />
institutions where, as a rule, many children are present. Since car drivers should drive past these areas very cautiously<br />
we found it important to install the devices at these locations first.<br />
In Niestetal you are using a special motif for the first time. It combines safety at a kindergarten with safety at an agency<br />
for senior citizens across the way from the kindergarten. Can you report on the experience with this idea thus far?<br />
As I mentioned before, the flexibility of design of the Displays was one of the selection criteria in favor of <strong>RTB</strong>, It was<br />
important for us that the Displays could be designed based on their location. For this reason the Display at this<br />
location has our Niestetal logo and a picture of a child with an older man. On the Display near the kindergarten a<br />
picture of young children is used. In the vicinity of schools older children are pictured.<br />
How do you rate the system at the present time?<br />
We hope that the Displays will significantly increase traffic safety, especially for children. The reactions to the<br />
Display up until now are, in any event, completely positive.<br />
Mr. Siebert, we sincerely thank you for this interview.<br />

Informative Journey into the Past<br />
“The Street as a <strong>Co</strong>ntemporary Witness of History”<br />
at the German <strong>Traffic</strong> <strong>Co</strong>nvention 2010<br />
The German Street and <strong>Traffic</strong> <strong>Co</strong>nvention 2010<br />
took place in the <strong>Co</strong>ngress Center Rosengarten<br />
in Mannheim from the 15th to the 17th of September<br />
2010. It was accompanied by the satellite<br />
exhibition Street and <strong>Traffic</strong> 2010. <strong>RTB</strong> was on<br />
location with a fair booth.<br />
The convention was organized by the Research<br />
Society for Street and <strong>Traffic</strong> Matters (FGSV),<br />
a non - profit technical - scientific association.<br />
Founded in 1924, it mainly supports continuing<br />
development of technical knowledge in the<br />
entire field of streets and traffic. In a cooperative<br />
manner, administrations, businesses and scientific<br />
agencies work together and send a total of<br />
2100 employees and members to participate in<br />
numerous expert commissions and committees.<br />
In the various presentation series, experts deal<br />
with current questions about the design of<br />
traffic space, street planning and traffic management.<br />
They also discuss the longevity of street<br />
construction.<br />
The satellite exhibition Streets and <strong>Traffic</strong> 2010,<br />
with its more than 100 exhibitors, attracted a<br />
great deal of interest as a meeting point for experts<br />
in the field. In this regard <strong>RTB</strong>’s exceptional<br />
fair booth puzzled many visitors. Certainly, many<br />
asked themselves, what do a sun umbrella and<br />
a folding chair have to do with a traffic convention.<br />
A closer look answered the question.<br />
<strong>RTB</strong> used two antique toy pedal cars, a Mercedes-Benz<br />
300 SL and a BMW 328 H, to emphasize<br />
the slogan of the exhibition “The Street as a<br />
<strong>Co</strong>ntemporary Witness of History”. Here the<br />
development of the street traffic census was<br />
of particular importance. Where students have<br />
often sat in their folding chairs along the side<br />
Dipl.-Ing. Martin Pozybill (Ministry for Environment, Ecological Protection and <strong>Traffic</strong> Baden-Württemberg) tests the traditional<br />
counting method at the <strong>RTB</strong> booth.
of the street and tried to coordinate a collection<br />
of singles pieces of paper with census information,<br />
modern counting devices mounted in guide<br />
posts will take over the task in the future. Of<br />
By the way. . .<br />
The full-scale originals of the two miniature<br />
old timers which were displayed at<br />
the <strong>RTB</strong> fair booth could recently be admired<br />
during the 3rd Hamburg-Berlin’-<br />
Classic Old Timer Rally.<br />
course, the visitors could get an impression of<br />
the radar technology involved but could also<br />
have a look at the time-tested <strong>RTB</strong> products<br />
Push Buttons and Acoustical Signal Transmitters.<br />
183 classic cars built between 1907 and<br />
1990 traveled from Hamburg to Berlin.<br />
After about 600 km through attractive<br />
German countryside the participants<br />
reached their goal on July 31. One could<br />
read the emotions in the facial expressions<br />
– the range went from pride to minor<br />
fatigue. Newcomers, old pros and<br />
prominent personalities such as Jochen<br />
Maaß (former race driver) or Detlef Buck<br />
(actor and director’) took on the physical<br />
challenge and tribulations.<br />
Once again it was an exceptional event<br />
with lots of fun and a good atmosphere.<br />
All those involved were in agreement on<br />
this.<br />

Early Technology<br />
Authentic Exhibition in the<br />
August Horch Museum in Zwickau<br />
The connection between history and the present<br />
is shorter than many people think. Especially in<br />
the signal manufacturing industry one has a<br />
direct connection to the automobile, because<br />
without the automobile traffic light facilities<br />
would very likely not exist. Therefore, we want to<br />
present a museum for technology here which documents<br />
the development of technical progress.<br />
Since September 2004 the August Horch<br />
Museum has been offering its visitors an authentic<br />
experiential exhibition on the subject of<br />
automotive history. The exhibition is housed in<br />
the restored buildings of the former Audi factory<br />
in Zwickau and is called “Relive Automotive<br />
History”. The reopening of the former office<br />
building and the Villa Horch in September 2005<br />
expanded the two-story exhibition area to<br />
almost 3,000 m2 .<br />
Many ideas started here and then had an influence<br />
on the entire German car manufacturing<br />
field: the pioneer spirit and the wealth of inventiveness<br />
of this over 100 year old tradition<br />
invite the visitors to discover the past now.<br />
Some real gems of the art of Saxon automotive<br />
construction, such as the Horch Phaeton from<br />
1911 and the compact car DKW F1 with the first<br />
production model front wheel drive or the<br />
elegant Horch Luxury-Models, testify to the<br />
highly sophisticated technology of times past.<br />
At the Intertraffic 2010 in Amsterdam another<br />
contemporary witness of automotive construction<br />
history drew the attention of many visitors:<br />
the DKW F8 at the <strong>RTB</strong> fair booth had a large<br />
number of admirers. After all, the engineering<br />
skills from the beginning of the automobile and<br />
in the current <strong>RTB</strong> products for street traffic<br />
technology form an attractive contrast.<br />
There is further information about the exhibition<br />
in Zwickau at www.horch-museum.de.

<strong>Co</strong>mprehensive Expansion<br />
Retrofitting traffic light facilities with net.1 in Gelsenkirchen<br />
Retrofitting a large intersection in Gelsenkirchen<br />
presented the authorities and the signal<br />
manufacturing industry with a considerable<br />
new challenge. In meeting this challenge net.1<br />
demonstrated its complete range of operative<br />
capability.<br />
Pedestrian crosswalk at the intersection Florastraße / Overwegstraße in Gelsenkirchen
In net.1 an intelligent field bus makes the integration<br />
of additional devices possible without<br />
necessitating an increase in the number of<br />
cables used. In Gelsenkirchen in particular this<br />
aspect was of enormous importance. The<br />
existing signal transmitter star cabling pattern<br />
would have, in the normal case, necessitated 52<br />
additional grounding cables for the retrofitting<br />
with signal transmitters for blind pedestrians.<br />
By using net.1 only 6 cables which could be<br />
installed simply in the existing duct system,<br />
were needed.<br />
Especially for this relatively complex junction,<br />
net.1 was expanded to make connecting a total<br />
of 32 signal transmitters with 230V for blind<br />
pedestrians possible. This expansion was important<br />
since 26 devices needed to be installed at<br />
the large intersection. This would not have been<br />
possible with the previous version of net.1.<br />
Independent of this concrete<br />
project, net.1 offers,<br />
in addition to the reduction<br />
of the size of the cable<br />
net, saving potential in<br />
the logic of the switching<br />
device. For example, the<br />
activation of the LED confirmation<br />
screen “Signal<br />
activated” is possible internally<br />
in net.1. In contrast<br />
to the strictly internal<br />
push button confirmation<br />
logic, the signals<br />
are activated centrally,<br />
to be exact in the net.1<br />
central module which is<br />
installed in the switching<br />
device.<br />
Thanks to these new<br />
possibilities an effective<br />
utilization of the existing<br />
grounding cable net is<br />
feasible and thus allows a<br />
simple and inexpensive<br />
retrofitting of existing<br />
traffic light facilities.<br />

This & That<br />
Vacation discovery<br />
In the vacation region Zillertal in Austria an <strong>RTB</strong> employee<br />
was more than surprised when she came upon a<br />
push button that was very familiar to her at the stations<br />
of the Narrow-Gauge Railway. Of course, she tested<br />
one right away and received the reliable announcement<br />
from the loudspeaker about when the next train to<br />
Mayrhofen or Jenbach would be departing. There were<br />
also push buttons to signal to the train engineer to stop<br />
at stations where the trains only stop on demand. This is<br />
simply another great example for the many different<br />
application possibilities for <strong>RTB</strong> products.<br />
Parking lots for trucks<br />
Goods valued at approximately 8 billion Euro are stolen<br />
from trucks annually. The General German Automobile<br />
Club (ADAC) tested the security at truck parking lots in<br />
eleven countries. Only nine parking lots met the high<br />
security standards. The European Union (EU) has<br />
recognized this problem and is supporting the project<br />
“Label” which is intended to help to certify parking lots<br />
in the future so that truck drivers can have a direct<br />
approach to guarded parking lots. Further information<br />
can be found at www.adac.de / lkw-parkplaetze and<br />
www.truckparkinglabel.eu.<br />
Endangered <strong>Traffic</strong><br />
A single sex act and then death – that is the fate of<br />
millions of day flies. This applies not only to the day flies<br />
but also to several Bavarian motorists. Along the Naab<br />
River in the Upper Palatinate <strong>Co</strong>unty Schwandorf<br />
the insect plague turns the streets into dangerous<br />
slides. The reason is that the day flies hatch and mate<br />
at about 10 pm when the illumination is appropriate.<br />
After mating the males die and fall to the ground<br />
where a dangerous slippery film is created. In order<br />
to counteract this, halogen spotlights are being<br />
installed directly under bridges to attract the insects.<br />
Then the flies would fall directly into the water after<br />
mating.
