摘要
灰色预测有其应用条件的限制,在交通流量统计的基础上,就不同累计时间的GM(1,1)交通量模型预测效果进行对比研究,可得出累计时间越长模型精度越高并且累计时间太短不宜用GM(1,1)建模的结论。
Grey prediction is limited by some application conditions. The study and contraction on the forecast model of traffic flows using GM（1,1） with different accumulative time based on the analysis of the traffic flows, can get the conclusion that model precision become higher as the longer accumulative time and it is unsuitable to use GM（1,1） in too short accumulative time.
