基于BP神经网络的公路网规模预测研究

摘要

The essay analyzes the relationship between highway network scale and economic development, selects the index by using Granger causality test method, establishes the prediction model of the highway network scale based on BP neural network, and predicts the rational highway network scale in Anhui province, with a view to promote the construction and development of highway network.%对公路网规模与经济发展的关系进行了分析,利用格兰杰因果检验法筛选指标,建立了基于BP神经网络的公路网规模预测模型,并对安徽省公路网合理规模进行了预测,以促进公路网建设与发展。
