基于GM(1,1)的道路交通事故预测

灰色预测法是将随机的原始数据序列用数据生成的方法生成规律性较强的新数列,以生成的新数列建立数学模型,GM(1,1)是一种典型的灰色模型.论文介绍数列灰色预测方法,通过道路交通事故预测实例,论述了GM(1,1)的建模过程,并对模型进行了检验.结果证明:针对我国道路交通事故典型灰色特征,用灰色理论进行预测研究是一种可行的方法,短期预测有较高的精度.

Prediction of Road Traffic Accidents Based on Model GM(1,1)

Gray forecasting is an approch in which a new series of data with a certain rule is generated from a random sequence of prime data by the method of data generation to build mathematical models.GM(1,1) is a typical gray model.This paper introduced a series of gray forecasting methods.Through actual examples of road traffic accidents forecast,the GM(1,1) modeling process was discussed and the model built was tested as well.The results obtained indicate that in view of the typical gray characteristics for road...
