车辆轨迹数据的若干处理方法研究

Methods to Process Vehicle Trajectory Data

从智能车路协同系统的概念出发,介绍了车路协同系统下的数据采集标准及轨迹数据特点,研究了轨迹数据处理的若干方法,包括车辆轨迹重构、交通参数提取、轨迹聚类等。

As a new stage of Intelligent Transportation System （ITS）, Intelligent Vehicle Infrastructure Cooperation System （IVICS） is put forward recently. Starting from the concept of IVICS, this paper first introduces the standards of data collection and their characteristics under vehicle infrastructure cooperation. Then, this paper discusses some methods to process trajectory data including vehicle trajectory reconstruction, traffic parameters extraction, trajectory clustering and so on. The methods mentioned in this paper can provide approaches and ideas for traffic control, guidance, incident detection, etc..
