基于移动通信网络空中接口数据的联合道路匹配算法
首发时间:2017-12-07
摘要:基于移动通信的交通数据采集时智能交通系统中新发展起来的技术,将车载手机及行人定位到电子地图上是其应用的基础,而地图匹配技术则是解决行人定位的关键。本文通过对行人手机在不同的道路网时产生的空中接口功率测量数据信息的研究,使用曲线拟合的算法思想,并结合道路的拓扑结构特点,提出了一种基于手机基站数据的道路匹配新算法。此算法可以缩小待选路段集,同时可以有效处理交叉口和平行路段等复杂情况,提高了匹配的准确率。最后,选取北京市海淀区部分特征明显的道路为测试区域,验证了此算法的可行性。

The Joint of Map-matching Algorithm Based on the Air Interface Data from Mobile Communication Network
Abstract:The collection of Traffic data based on mobile intelligent transportation system developed a new technology, the car phone and pedestrian positioning is the foundation of its application to the electronic map,while map-matching technology is the key to solve the pedestrian positioning. we use the 4G interface measurement data information for research when the pedestrian is in different road network, using the thought of curve fitting algorithm, and combining with the characteristics of the topology of the road. This paper proposes a new path matching algorithm based on mobile phone base station data,and the algorithm can reduce the set of selected sections and can effectively deal with complicated situations such as intersections and road sections, and improve the matching accuracy. Finally, we selected the road of Beijing haidian district which has obvious features of roads to verified the feasibility of this algorithm.
