我们介绍了我们使用基于短信的系统的经验，该系统仅基于现有的蜂窝和GPS网络提供交通信息。其目的是允许开发不依赖中央当局或复杂的网络托管的信息服务。我们开发了我们的系统，并将其应用于吉尔吉斯斯坦比什凯克的私营马什鲁卡公交车网络。然而，我们的目标是更广泛地解决发展中国家的临时共享交通系统问题。车辆上放置了一个定制设计的GPS-GSM单元，用户可以使用自己的未启用GPS的手机通过短信查询我们的服务器。我们报告了我们的位置命名方法的准确性和对巴士到达时间的估计。此外，我们总结了对巴士司机和巴士乘客的访问，表达了他们对该系统的看法，并概述了未来工作的方向。我们的系统是解决发展中国家长期缺乏交通信息的基层解决方案。
We present our experiences with an SMS-based system for providing transit information based solely on existing cellular and GPS networks. The aim is to permit the development of information services that do not rely on a central authority or complex web hosting. We developed and applied our system to the network of privately-run marshrutka buses in Bishkek, Kyrgyzstan. However, our goal is to more broadly address issues of ad-hoc shared transportation systems in the developing world. A custom designed GPS-GSM unit is placed on a vehicle, and users can query our server over SMS with their own non-GPS-enabled cell phones. We report on the accuracy of our location naming approach and estimates of bus arrival times. In addition, we summarize interviews with bus drivers and bus riders relating their views of the system and outline directions for future work. Our system is a grassroots solution to the persistent lack of transport information in developing countries.
