The need to make optimal
use of the restricted space on VMS (Variable Message
Signs) did determine the decision for a slightly
condensed design of the letterforms. Knowing that
condensed letter forms are less legible than standard
ones the IIID team with world renowned type designer
Prof. Erik Spiekermann worked hard to outbalance
this disadvantage for greater flexibility of displaying
and structuring content on VMS. The result is a
brand new typeface, called "Tern" (for
"Trans- European Road Network").
As with the symbols/pictograms the elaborated "Tern"
has been designed in a vector graphics based format
for general use and – in bitmap form –
for use on VMS displays. The latter is available
in 4 sizes:
TernVMSonefour
(body height = 14 pixels), TernVMStwozero (body
height = 20 pixels) and TernVMSthreeone (body
height = 31 pixels).
One additional size was designed to facilitate
tests in comparison with the fonts currently used
on many LED based VMS and to allow for their immediate
substitution, if deemed appropriate: TernVMStwofour
(= 24 pixels high).
All fonts are available in Latin and Greek character
sets.
Find details on the functionality
of "Tern" in the Typeface
test report (PDF).
