Cellular Phone Based Real-Time Bus Arrival Information Systems
Dihua Sun, Liping Fu · 2004
This paper describes a conceptualization of a cellular phone based real-time bus arrival information system. The system is proposed to take advantage of wide-spread use of cellular phones and uses them both as a data source and information distribution media. As a data source, cellular phones are used as location referencing devices based on the principle of radio triangulation, obviating the need to install dedicated location systems such as GPS and communication links. As an information dissemination medium, cellular phones and wireless communication network are used as a low-cost platform for distributing bus arrival information. The architecture of the proposed system and its operating mechanisms and key features are described.
