城市交通流信息相似性分析与研究

信息处理日益成为智能交通系统发展中的一个重要环节，它要求智能交通系统不断集成新的信息技术以实现信息的采集、融合、组织和处理。生物信息技术在ITS信息处理中的应用成为其中新兴的研究方向。为证明交通信息具有生物遗传属性，本文定义了相似系数及波动系数作为交通流的相似性判据，并对城市交通流单点流量信息在时间轴上的相似性进行实验与数据分析，从而证明了其相似性的存在。文章还对该特性在交通流信息处理中的几种可能应用进行了分析和讨论。

Analysis of Similarity for Urban Traffic Volumes

Information processing is increasingly becoming one of the most important topics in the development of Intelligent Transportation Systems (ITS), which has been benefiting from the new developments in information technology, such as information collection, fusion, organization, and management. The biological information technology has become a new research area which can be useful in the information processing for ITS. In order to verify the existence of biological heredity in urban traffic information, a similarity coefficient and a fluctuation coefficient were defined as criteria to analyze urban traffic volumes with experiments in this study. Results of the analysis proved the existence of similarity for these volumes. This paper also proposed several possible applications of the similarity attribute of traffic data in the ITS information processing.
