A bus stop sign capable of providing detailed bus schedules includes a storage unit, a detecting unit, a communicating unit, and a control unit. The storage unit pre-stores a table recording identifications of a plurality of mobile terminals, identifications of a plurality of bus terminals, and stop information of the bus stop sign along bus routes of the bus terminals. If the identifications of the mobile terminals obtained by the detecting unit match one or more identifications recorded in the table, the control unit obtains identifications of bus terminals recorded in the table corresponding to the obtained identifications, and controls the communicating unit to transmit the obtained identifications to the server. The server determines the current location of the nearest bus terminal travelling toward the bus stop sign and feeds back the current location of the nearest bus terminal to the mobile terminal. A related sever is also provided.

摘要:
A bus stop includes a storage unit, a communicating unit, a display unit, and a control unit. The communicating unit communicates with a server which is in communication with a plurality of buses, a plurality of stops which the buses will pass, and current locations of the buses. The display unit displays at least one route consisting of a plurality of bus stops including the bus stop. The control unit generates a request signal carrying the location of the bus stop to the server. The server determines current locations of the buses on a route which includes the bus stop, compares the real-time locations with the location of the bus stop to select a nearest bus travelling towards the bus stop. The display unit display a mark marking the bus stop. A related system is also provided.
