Surrounding traffic information and warning Goal: In shortInternational 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 13 June, 2012 Final Event Örnkoldsvik, Sweden 2
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. 13 June, 2012 Final Event Örnkoldsvik, Sweden 3
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.) 13 June, 2012 Final Event Örnkoldsvik, Sweden 4
Methodology, simplified Collecting, reviewing & evaluating Signs, pictogramsInternational Institute for Information Design and related information Processing for enhanced visual quality 1 MoA * * See: From optometry to road saftey – A design process to enhance visual informatio for safety critical situations http://www.iiid.net/Safeway2SchoolReport.aspx 13 June, 2012 Final Event Örnkoldsvik, Sweden 5
1 Collect, review and evaluate 92 Signs/pictograms Related standards and from 37 countries regulationsInternational Institute for Information Design Evaluation of examples for most suitable to be reworked for • improved visual quality • updating international regulations Example found in Portugal 13 June, 2012 Final Event Örnkoldsvik, Sweden 6
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) 13 June, 2012 Final Event Örnkoldsvik, Sweden 7
2 Enhancing visual quality cont. Enhanced symbol (pictogram) and signsInternational Institute for Information Design to be commonly used for faster recognition VMS Road signs ROAD USE • long range visibility (plates/signs) for being seen earlier • being visible despite of glare • low resolution use for LED signs (VMS) OTHER USE • small scale visbility for small print/screen use (maps/in-car navigation) 13 June, 2012 Final Event Örnkoldsvik, Sweden 8
Visual discriminability performance Simulator Test (University Stuttgart/Fraunhofer Institute): Comparison of long distance visibility performance of 4 signsInternational 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) 13 June, 2012 Final Event Örnkoldsvik, Sweden 9
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 13 June, 2012 Final Event Örnkoldsvik, Sweden 10
