Transit forecast system is an important part of Urban Intelligent Public Transportation System.It can effectively optimize public transportation and improve the efficiency of people traveling. bus forecast station system based on radio frequency technology and STC12C5A microcontroller is designed in this paper,which can replace the common bus forecast station system based on GPS technology. The system relays the bus departure and arrival information transmitted to the downstream site through radio frequency technology. voice and LED display on the site are two ways to predict the arriving bus information to facilitate the public to select the appropriate bus ride . This paper mainly describes the composition of the system and hardware design.
