短期交通流的局部分形研究

Study on Local Fractal of Short-term Traffic Flow

根据短期交通流的混沌与分形特征，提出利用时间序列的最小覆盖维方法分析其局部分形特性，研究了最小覆盖维与短期交通流量波动的关系，运用最小覆盖维估计交通流的发展和变化趋势。

The dimension of minimal cover is developed to analyze local fractal of short-term traffic flow according to the chaos and fractal in it. The relation between the dimension of minimal cover and the short-term traffic flow fluctuation is deduced. The dimension of minimal cover is applied to estimate the trend of traffic flow.
