Development of a novel bus location system using wire-area wireless sensor networks and its demonstration experiments

本研究利用广域无线传感器网络，开发了一种新型公交车辆定位系统，能够以较低的运行成本实现连续运营。该系统通过无线传感器网络中的多跳通信，在不增加通信代价的情况下，采集公交车辆的位置信息，并提供公交运营信息。演示实验在爱知县日新市运营的一处“库鲁林公交”运营区域进行。结果，该系统被证实，即使在行驶中的车辆和树木的影响下发生数据时，在公交车站的显示面板上也几乎准确地指示出公交车行驶的各个路段。

This research developed a novel bus location system capable of continuously achieving operation at low running costs by using wide-area wireless sensor networks. The system can collect bus location information and deliver bus operation information without communication costs by multi-hop communication in wireless sensor networks. Demonstration experiments were held in an operation area of "Kururin Bus" that is operated by Nisshin City, Aichi Prefecture. As a result, the system was confirmed that respective sections on which a bus was traveling were almost accurately indicated on the display panel of bus stop even when data occurred from influences of traveling vehicles and trees.
