ABSTRACT:
A message display monitor for a bus is disclosed in combination with a bus destination sign. A changeable alphanumeric destination sign (10) is automatically controlled by a control system (16) to display a selected message from a message memory (14). The message is selected by a manually actuated selector (12) which addresses the memory (14) according to a manual input which is specified in a look-up table which contains multiple messages. An electronic alphanumeric display monitor (18), specifically an LED display, is connected with the message memory (14) through a monitor control system (20) so that it will show the bus driver the message selected from the memory.
