Evaluation of location estimation method for bus location system based on wireless sensor networks

Abstract

Abstract One of methods to improve the convenience and quality of service provided by bus service operators is to implement a bus location system capable of providing positional and operation related information to the users. We have previously proposed and implemented a novel global positioning system (GPS)-based bus location system using wireless sensor networks interspersed in the city, which does therefore not entail any communication costs. In this paper, we propose a new bus location method that does not use GPS positioning, and thus reduces the manufacturing cost of the transceivers mounted on community buses. We develop prototype devices and conduct an on-road demonstration experiment, confirming that the required bus location information can be estimated with sufficient accuracy.
