Public Information System

       A Public Information System is a system designed to present information to the public or large audience all at the same time.
      These systems make use of large display technology such as bill-board sized LED displays and networked display monitors.

      For example:

     - In airports, presenting the arrival and departure information on monitors and electronic boards is essential for the smooth operation of the airport.

     - Train stations also need this information.

     -Sometimes major sport events and public gatherings will make use of public information systems.

     -Motorways have gantry displays for the latest situation or speed restrictions.

Why is it important that the information is up-to-date?

    These systems need to be easy to update and maintain to ensure that the public is viewing the most recent information.
