阐述了灰色理论,建立灰色预测模型,并用该模型进行交通量预测。预测结果显示:较惯常的预测理论,灰色预测模型处理较少的模糊数据具有明显的优势,预测结果具有更好的精度等级。 It expounds the gray theory, establishes the gray prediction model, and uses this model to forecast the traffic volume. The prediction results show that the gray prediction model has more advantages than the usual prediction theory in that the gray prediction model can process less fuzzy data, and the prediction result has better accuracy grade.
