ABSTRACT:
A destination sign for buses is provided with means for adding a route number to the display device independently of the destination name displayed on the sign. The destination sign is of the electronic type in which a long destination name is displayed by showing two or more word units in time sequence on the same display device (10). The word units are stored in memory (18); a destination name selector (14) and logic means (16) addresses the desired combination of word units in sequence. A route number selector (24) generates a route number signal independently of the destination name selector. The memory and the route number selector are selectively coupled by switching means (20) to a character generator (22) which controls the energization of the display device according to the characters to be displayed in the destination message. A route number flag signal is stored in memory with short destination names and the flag signal controls the switching means so that the route number is automatically displayed with the short word unit of the destination name.
