Short-Term Traffic Fractal Research Based on Phase Space Reconstruction
【摘要】 应用基于混沌与分形理论的相空间重构技术对短期交通流量变化时间序列的分形特征进行了研究,通过G-P算法在MATLAB中的实现,求解出交通流量变化时间序列的关联维数,最后对实际采集数据进行了实例分析。
【Abstract】 According to the phase space reconstruction technology based on the chaos and fractal theory,the fractal characteristics of the short-term traffic flow time series are studied in this paper.Through the implementation of the G-P algorithm in MATLAB,its correlation dimension is worked out.Finally,the real collected data are analyzed through the example.
