Many existing bus location systems use a cellular network for collecting bus location information and for delivering bus operation information to bus stops. On the other hand, in order to operate the bus location system continuously, local governments and small-and-medium-sized bus companies that operate a community bus have an overwhelming need to reduce running costs as much as possible. In this paper, the authors propose a novel bus location system using Wireless Sensor Network that requires no communication cost. In the proposed system, a wireless sensor network consists of multiple IEEE802.15.4-compliant sensor nodes that are installed in buses, bus stops and street lights along bus routes, and some information are transmitted on the network. The authors conducted a prototype system in some bus service area. As a result, it was confirmed that a bus location system can be realized using the wireless sensor network built in the actual environment.
