Abstract

FM Subsidiary Communication Authorization (SCA) has been used to broadcast background music for a long time. Analog audio programs or digital data transmission services, utilizing SCAs, such as paging, stock market and headline news updates are common in people's daily life. Some demonstrations have been offered in the past to broadcast fax messages and some studies dealing with broadcasting video programs over the FM SCA channels. This paper focuses on using the FM SCA subchannel to transmit bus service status. This application provides the transmission of accurate status of public bus transportation services in order to offer better services. The status can be displayed on bus stations display boards or on personal computer receivers.
