Symbols

From AIGA.org:

The complete set of 50 passenger/pedestrian symbols developed by
AIGA is now available on the web, free of charge. Signs are available
in EPS and GIF formats.

About the symbol signs

This system of 50 symbol signs was designed for use at the crossroads
of modern life: in airports and other transportation hubs and at
large international events. Produced through a collaboration
between AIGA and the U.S. Department of Transportation (DOT),
they are an example of how public-minded designers can address a
universal communication need.

From NPR.org:

Incensed by a "no tresspassing" sign, Jeff Deck launched a cross-country trip to right grammatical wrongs.

Icon FAIL

From Yahoo.com:

The warning for the TPMS lights up when one or more of your vehicle’s tires is 25% below the manufacturer’s recommended pressure. The system is now required on all vehicles starting with the 2008 model year.

The issue here seems to be that the public hasn’t been properly educated on the warning symbol, which is supposed to be “idiot proof” and understandable across a wide variety of cultures and languages. Yet 46% of drivers couldn’t figure out that the icon represents a tire and 14% thought the symbol represented another problem with the vehicle entirely, according to Schrader.
