Trafiko Sans

Trafiko Sans is the brand typeface of Trafiko. It is a derivative of Plus Jakarta Sans, designed by Gumpita Rahayu of Tokotype for the Plus Jakarta "City of Collaboration" program (2020).

Styles

Two families, each with seven weights from ExtraLight (200) to ExtraBold (800):

• Trafiko Sans — upright
• Trafiko Sans Italic

Both are also available as variable fonts with a wght (200–800) axis.

Repository layout

sources/         Glyphs sources (TrafikoSans.glyphs, TrafikoSans-Italic.glyphs)
fonts/ttf/       Static TTFs, one per weight and style
fonts/variable/  Variable fonts (wght axis)
fonts/webfonts/  WOFF2 versions of all of the above, plus Latin-only subsets

Which file to use

• Web: fonts/webfonts/TrafikoSans-Variable-Latin.woff2 (and TrafikoSans-ItalicVariable-Latin.woff2) — a Latin-only subset of the variable font (~25 KB vs ~60 KB) covering English, Swedish and Western European languages, with tnum, case, kerning and fractions retained and the stylistic sets stripped. Use the full TrafikoSans-Variable.woff2 if you need the complete character set or the stylistic sets on the web.
• Apps (e.g. React Native): the static per-weight TTFs in fonts/ttf/.
• Print / design tools: fonts/ttf/ or fonts/variable/ — full character set and all OpenType features.

OpenType features

Stylistic sets (ss01 Lancip, ss02 Lurus, ss03 Lingkar alternates), case-sensitive forms, fractions, superiors/inferiors, localized forms — inherited from Plus Jakarta Sans — plus tabular figures (tnum), added in Trafiko Sans: all ten digits share a fixed advance width per weight, for use in tables, timetables and numeric UI.

font-feature-settings: "tnum";

font-variant-numeric: tabular-nums;
