交通运输工程与信息学报

为了支持厦漳泉同城化发展战略,方便市民出行,促进三地交流,本文构建了简易的云服务中心,设计了公交同城化信息查询系统。采用了网关短信技术开发了短信平台,遵循GSM 03.40规范开发了长短信功能。同时还设计了搜索树算法、同城化线路换乘算法,实现公交换乘方案的求解,并应用折半查找算法优化求解效率,降低计算资源的消耗。该系统的架构与算法设计独特,能够承受公交高峰期时间巨大的查询压力,引导出行者优先使用公交资源。

An information query system for bus integration based on cloud service was constructed in order to support the development strategy of Xian-Zhang-Quan city circle and to facilitate the public transportation and exchanges among the three cities. In this system, an SMS platform was developed based on the gateway SMS technology, and the long message function was developed according to the GSM 03.40 protocol. Meanehile, the searching tree algorithm and the bus integration transfer algorithm were designed to provide bus transfer solutions. The calculation efficiency have been optimized by applying the binary search algorithm in order to reduce the consumption of computation resources. The architecture and algorithm design of this system was very unique, able to withstand high inquiring pressure during the peak hour. It will guide the travelers to use the public resources with the first priority.
