基于手机切换变化模式的道路匹配方法

The Map Matching Method Based On Cell Phone Handover Pattern

应用手机定位技术进行交通数据采集是当前国内外研究的热点,其中道路匹配是技术应用的关键环节之一。本文重点研究如何利用手机发生连续切换变化的通信数据信息进行道路匹配,其基本原理是利用手机在通信网络层的变化模式反推在道路网络层的变化模式,本质上可归结为模式匹配问题。本文主要内容包括:基于手机切换变化模式的道路匹配方法的基本原理和核心思想;界定与GPS坐标定位的道路匹配方法的区别;创新地提出通信网络层变化模式与道路网络层变化模式的关联技术,即道路切换序列标定方法;最后,结合城市中心区某道路的实测手机通信数据进行了实证分析。

The application of cell phone location technology for traffic data collection has been hot recently and the map matching is one of the key points. In this paper the emphasis is placed on how to use continuous handover information of the cell phone sample for map matching, whose basic principle is to get the pattern in the road network by using the pattern in the communication layer. The paper mainly contains： the principle of map matching based on cell phone handover pattern; the difference between the GPS coordinate based method and the handover based one; the technology combined pattern in the communication layer with one in the road network, that is the way to calibrate the handover pattern of the road ; finally the method is proved by the real communication data.
