【摘要】 详细地探讨路段自由流车速定量分析的一种新的算法———BP (BackPropagation)神经网络法 ,并与多元线性回归法相比较 ,认为BP神经网络法优于多元线性回归法。为了解决数据不足问题 ,还用多元线性回归法为神经网络法提供了典型学习模式对。更多还原

【Abstract】 Quantitative analysis of influence factors of free flow speed by back propagation artificial neural network algorithm is discussed in detail. It is concluded that the method is superior to linear regression method. The later can produce typical study examples to the former.更多还原
