The Aesys line and destination indicators are part of a complete, modular and comprehensive passenger information system consisting of other Aesys systems that can be integrated with each other. The information shown on the outside can be resumed and enriched inside the bus thanks to the upcoming audio-visual system and the on-board multimedia system, thanks to which it is possible to convey, in addition to the information relative to the route, also company information or different information type with a modern and attractive layout, which provides information on the next stop but also general and advertising announcements.
