This paper analyzes systematically widespread problems about the most of bus stop boards existing in domestic ordinary, which include incomplete bus information in one area, lack of traffic information about the city and low humanity. In view of these problems, the paper proposes conceptual design of a new bus stop board on the basis of control ability and opening information. The conceptual design uses the opening information mode, combines with the map of the bus lines, and facilitates passengers by two ways — station index and line index, which can give all information of the bus lines about one area. By the new bus stop board, passengers could obtain not only the information of the bus line and information of lines in one station, but also important bus-stations, passenger transport hubs, geographical position information and so on. Compared with the old bus stop board, the new one improves the opening information of the bus stop board system and upgrades the level of humanization degree.
