Abstract

Abstract
Road traffic information has been one of the important elements for traffic information
systems. The information can be found on the road where Variable Message Sign (VMS) and
other platforms have been widely utilized for such application. These overwhelming
majorities of traffic information sources provide real-time traffic information, aiming at helping
drivers make better decisions on choosing a correct traffic route on the basis of current traffic
state. However, it is an unusual sight to view the full scenarios of the system with the view
from the drivers themselves. Therefore, smartly presenting the information to the road user
has a potential to support the road user to receive and interpret the information in a more
effective way. Traffic information presented in different styles may enhance the
attractiveness of the information itself. Considering this, we design this study to find out
whether there is a refined relationship between the specific presentation style and the driving
behavior.
As a starting point, this study tested the assumption that the probe vehicle could provide
reliable and sufficient amount of data that could represent travel time information which then
can be transformed into various presentation style. VISSIM 5.0 is used to generate travel
time data on a hypothetical network. Average travel time on links are analyzed for various
p
the results of travel time provided by probe in a more understandable visual fashion (color
coded design).
Later, user testing upon preference of the drivers towards different types of traffic information
presentation style is conducted. A picture is often cited to be worth a thousands words and,
for some tasks it is clear that a visual presentation such as map is dramatically easier to be
used than other textual or spoken description. Visual displays become even more attractive
to provide orientation or context, to enable selection of regions and to provide dynamic
feedback for identifying change such as dynamic traffic congestion map. In what concerns
the visual information, systems can present information using graphics, symbols or even
written messages. A stated preference user test is conducted and questionnaires with
different types of traffic information presentation style are distributed to the respondents. An
underlying question is basically about whether and how the presentation styles of traffic
information affect the driver in making their decision. The study addresses a wide range of
alternative styles of in-vehicle traffic information as well as stationary information in different
driving scenarios (stop and go and congested). The analysis is carried out which contains
various trip variables, including route selection characteristics, travel purpose and actual
observable traffic conditions en route such as level of congestion, variables pertaining to the
information to which is being displayed and also psychological factors based on personal
attributes and the experience of the individual drivers. It is assumed that drivers are
influenced by these variables and factors of making decisions whether to acquire and refer to
traffic information in choosing their route.
Our results revealed that in case of in-vehicle information, presentation style of traffic
infor
presenta
reason for this preference is the presence of the buildings which provides additional
orientation information. Different behavior patterns could be observed when confronted with
more realistic situations. Our observations demonstrate that the drivers are more likely to
divert their route only in rush trip.

In case of stationary information, again, we found no evidence that presentation style of

Zusammenfassung

Zusammenfassung

Straßenverkehrsinformationen sind eine der wichtigsten Elemente in
Verkehrsinformationssystemen. Diese Informationen lassen sich auf der Straße in Echtzeit
erfassen, z.B. durch das Wechselverkehrszeichen (Variable Message Sign -VMS). Eine
Vielzahl von Verkehrsinformationsquellen liefern aktuelle Verkehrsinformationen, welche den
Autofahrern helfen, bessere Entscheidung bei der Auswahl des richtigen Verkehrsweges
anhand der aktuellen Verkehrslage zu treffen. Allerdings wäre es dem Fahrer nicht von
Vorteil, alle aktuellen Verkehrsinformationen aus der Fahrerperspektive zu erhalten. Daher
ist eine elegante Bereitstellung der Informationen maßgebend, um diese effektiver zu
empfangen und zu interpretieren. Unterschiedlich dargestellte Verkehrsinformationen
können deren Attraktivität vielfach steigern. Unter Berücksichtigung dieses Aspektes führen
wir diese Arbeit durch, um herauszufinden, ob es eine relevante Beziehung zwischen
spezifischer Präsentationsweise und dem Fahrverhalten gibt.

Zu Beginn dieser Studie wird die Annahme getestet, ob ein verwendetes Versuchs-Fahrzeug
eine zuverlässige und ausreichende Menge an Daten liefert, wie z.B. das Vermitteln von
Informationen über die Reisezeit durch verschiedene Darstellungsarten. Für diese Studi
