2. Surrounding traffic information and warning
Goal: In short
International Institute for Information Design
To research and design information
• to effectively warn road users on the fact
that children are on the road,
• taking into account today’s demanding traffic
situation

3. Surrounding traffic information and warning
Motive:
International Institute for Information Design
The graphical representation of the sign as currently proposed by
UNECE ITC, based on sign “A, 13 - Children” is – along with all
other signs of the Convention on Road Signs and Signals, Annex 1
– dating back to a time (1968 and way before), where traffic was
less demanding:
• There were far less vehicles,
• which were only capable of low speeds, moving
• on less roads allowing only for much lower velocities than today.
• Traffic was by far less international.
• Information density provided on roads was by no means as
high as today.

4. Surrounding traffic information and warning
Solution: To meet the requirements of the
demanding traffic situation of today,
International Institute for Information Design
the visual quality of the sign is raised by a method developed by
IIID in EU FP6 research project SOMS/In-Safety -
• allowing a driver to discriminate (“read”) and understand the
sign from a much greater distance than currently possible
with sign(s) in use
• providing a driver with means to react at greater distance
(earlier) to the signs message, and adjust the driving mode
accordingly (eg. Slow down and watch out, break etc.)

6. 1 Collect, review and evaluate
92 Signs/pictograms Related standards and
from 37 countries regulations
International Institute for Information Design
Evaluation of examples
for most suitable to be
reworked for
• improved visual quality
• updating international
regulations Example found
in Portugal

7. 2 Enhancing visual quality
Processing for enhanced visual quality,
International Institute for Information Design
adhering to MoA (Minute-of-Arc)
design method for:
ROAD USE
• long range visibility (plates/signs) for 1 MoA
being seen earlier (= more time for drivers
to react) = safety improvement
• being visible despite of glare
• low resolution use for
LED signs (VMS)
SW2S School
OTHER Bus (Stop) sign
• small scale visbility for
small print/screen use
(maps/in-car navigation)

ROAD USE

9. Visual discriminability performance
Simulator Test
(University Stuttgart/Fraunhofer Institute):
Comparison of long distance visibility performance of 4 signs
International Institute for Information Design
(pictograms) – left to right.:
1st: SW2S & Sweden
2nd: Austria
3rd: UNECE ITC (international recommendation of the UN on how
the appearance of the sign should look like)

10. Standardisation
Due to lowest performance of UNECE ITC example,
proposal to substitute the sign/symbol in the
Consolidated resolution on Road Traffic (R.E.1). Annex 1,
International Institute for Information Design
Recommendation 2.2. (United Nations, Economic Commission for
Europe, Inland Transport Committee, 1998),
with the sign developed in SW2S
