移动数据的交通出行方式识别方法

Research of the identification methods for transportation modes based on mobile data

识别用户出行的交通方式,对理解用户移动性、交通状况的分析和预测、社会活动模式挖掘等方面起着非常关键的作用。随着无线网络技术的快速发展,越来越多的传感器被用于收集移动数据,如何通过收集的信息准确地识别用户不同的交通出行方式,近年来得到了广泛的研究。针对已有的从不同角度识别交通方式的方法,首先介绍了每种方法的具体内容及应用,然后对不同方法进行分类研究,并重点分析了各类方法的特点,分析几种不同方法在不同条件下的识别精确度,最后,给出了交通方式识别方法的进一步研究方向。

Identification of different transportation modes in the process of user travel plays an important role in understanding individuals＇ mobility,analyzing and forecasting traffic conditions and mining social activity pattern.With the rapid development of wireless network technology,more and more sensors are used to collect mobile data.Specially,how to accurately identify user＇s different transportation modes from the collected data has been extensively researched in recent years. In addition,the methods of identification proposed from different points of view to solve the problem were studied in this paper. Each method and its application was introduced in detail and then classified and researched,respectively. The focus of analysis is put on the characteristics of each method. The levels of the recognition accuracy of different methods under different conditions were analyzed in table form. Finally,the research directions of the identification methods for transportation modes were further discussed.
