Fractal Dimension and Forecasting of Traffic Flow for Freeway Based on Phase Space Reconstruction
Shunying Zhu · Journal of Chongqing Jiaotong University · 2007
By calculating the Hurst Index of the short time traffic flow in variant time scales for freeway,a fractal dimension was put forward.It showed that the interval time of traffic flow was shorter,the fractal dimension was bigger,and the structure was more complex.So it is more difficult to forecast.We present a new forecasting method-moving average nearest neighborhood forecasting method,which is based on the phase space reconstruction and combining with the moving average forecasting and the nearest neighborhood method.The efficiency of the method was proved by theory and actual traffic flow.
