The Passenger Emergency Communication Unit (PECU) is installed on-board public
transportation vehicles and provides critical emergency communications between the
public, public transportation drivers and/ or control centres. The design of the PECU
device has been reimagined, giving it an artistic appeal by forming it in a shape
that resembles a microphone. At the same time, the device clearly identifies itself to
the human subconscious as an emergency device, therby allowing the public to
engage in its easy and intuitive use.
