FF Transit is a highly legible typeface that works well for readers who need quick orientation while en route. Designed to blend aesthetic quality with legibility, it was originally designed by MetaDesign in Berlin for the official use of the Berlin Public Transportation Services (BVG) and Düsseldorf Airport. Based on Frutiger (licensed from Linotype), it is a freshly drawn, narrow version with original italics and many variants made for rigorous applications in a complex signage system. Front and Back are subtle variations which compensate for the visual distortion that appears on illuminated signs which are either backlit or lit from the front. These variants are also useful for the compensation sometimes required by white text on a black background.
