The automatic broadcast system automatically plays the following information within a depot through the rules which are artificially given or established in advance: the depot introduction, the advertisement, the number of orders for vehicles departure and so on. This aims to inform the passengers promptly each kind of depot’s immediate information, the convenient depot-dissemination information as well as the passenger oriented traveling navigation information. The information can be broadcast with the radio announcer artificially or be disseminated as the broadcast leisure music or the station’s fixed propaganda.
