区域高速公路网是区域社会经济发展的重要基础设施,为预测区域高速公路网交通量,引入经济学中的柯布-道格拉斯生产函数,以人均GDP、人口密度为参数构建运输需求函数,基于运输需求函数构建区域高速公路网交通量预测模型。模型能以简单的因素分析基础,对区域高速公路网交通量进行预测,为区域公路网交通量预测提供了新的思路决策依据。
Regional highway network is an important infrastructure for regional social and economic development. In order to forecast the traffic volume of expressway network in the region, the Cobb-Douglas production function in economics is introduced to construct the transport demand function based on per capita GDP and population density. Demand Function to Construct Regional Expressway Traffic Volume Forecasting Model. The model can be based on a simple factor analysis to predict the traffic volume of the expressway network in the region, which provides a new basis for decision-making of the traffic volume forecast for the regional highway network.
