Information is needed “to know”. Knowledge is power. Providing information in public space in a way that improves perception of information fosters empowerment of citizens. To this end, Tern Symbols have been introduced to measurably improve visibility of information.

Maximum visibility of information on signs – improving road safety and fostering inclusion

Tern Symbols are crafted to maintain maximum visibility of visual information, despite difficult circumstances, such as movement at high speed, short viewing duration, long viewing distances and bad viewing conditions. This is crucial for adequate information perception in vehicular road traffic, as well as for citizens effected by visual impairments to profit from inclusive information.

Reliable principles and new possibilities

Through the employment of the MOA Design Method’s principles, maximum visibility is established for symbols, which can be precisely followed up through calculation. This also allows to precisely determine viewing distance.

The MOA Design Method represents the result of insights starting 2005 with EU funded project SOMS/In Safety, followed by project Safeway2school. Continuous research thereafter led to the discovery of the method.  Tern Typeface, which adheres to the principles of the MOA Design Method, has become the standard road signage typeface in Slovakia, and is legally binding for use on Austria’s road signs. The Netherlands use Tern VMS Typeface countrywide on Variable Message Signs on roads.

Tern Symbols System content

The Tern Symbols Set follows the logic of the system of road signs shown in Annex 2 of the UN’s Vienna Convention on Road Signs and Signals, done in Vienna, 1968 (called hereafter “VCRSS”). A country having signed this law of nations is obliged to use its signs on all roads.
