Preface

The Finnish traffic sign typeface contains a lot of errors and problems. I ended up asking about the typeface used for upcoming renewed signs from Finnish Transport Agency (currently Finnish Transport Infrastructure Agency), and the conversation in Twitter lead to a CC0 release of the original typeface drawn in 1960's.

Tie is a typeface conversion of the original Finnish traffic sign typeface that is available at Finnish Transport Infrastructure Agency page.

Usage / Installation

  1. Download the .OTF and .WOFF versions from the /fonts folder of this repository
  2. Drag-n-drop / copy the downloaded files to Font Book (on OSX) / Fonts (Control Panel) (on Windows)
  3. Open your preferred text / visual editor and start making your own traffic signs

Conversion

The conversion was made using Adobe Illustrator, by defining the x-height, cap height, ascender height and descender height based on the following letters:

dxHP

the method is described in a tutorial video on YouTube.

After that, the letters were copied one by one to Glyphs app and scaled with same proportions.

Spacing of the typeface was done using the original spacing tables, from page 287->.

Kerning tables aren't done, as I felt a bit unmotivated since the original kerning is somewhat bad.

Observations made during the conversion

  • Intriguingly, the cap height and the ascender height are the same
  • Originals, especially the lower-case ones, contain a lot of artefacts, and is not clear how to fix them

Problems fixed

I was brave enough to fix some of the problems that exist in the original typeface

  • Letters a, å, ä and y had some artefacts, so I removed them
  • Spacing (still pretty much WIP)
  • Semicolon spacing is taken from colon
  • Colon spacing is taken from from period
  • ! spacing is from capital I
  • ? spacing is from capital S

Existing problems and issues (TODO)

  • Artefacts from the originals should be removed and fixed
  • Kerning is not done (feel free to contribute, the information exists is on page 293->)
  • Some curves aren't curves - they have angular shapes
  • Missing: Cyrillics and their spacing, from page 298->

Major improvement ideas - How to make Tie actually work for traffic signs

  • Design is not pretty by the standards of modern typography
  • Design doesn't work well for traffic signs, as the glyphs become interchangeable when seen from a distance
  • Missing a LOT of glyphs
  • parenleft, and parenright seem like they are originally from another typeface (should have a thicker stroke)
  • There seems to be multiple originals, parenleft & parenright are good examples of these, compare with the traffic sign example
  • Human visual perception should be compensated with adding an overshoot (=placed below the baseline) to letters such as the letter o.
  • Add support to more glyphs
  • Add arrows and other signs used in the Finnish traffic signs to the typeface itself as ligatures, so they can be used whilst using the typeface itself
  • Missing different weights and styles (this could improve readability depending on the context)

TLDR: Not very well suitable for the traffic sign system at all

Potential benchmarks (Some european wayfinding typefaces)

  • Tratex
  • Dansk Vejtavleskrift
  • British Road Alphabet
  • DIN1451
