| 摘 要： | 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。

| Abstract: | The regional expressway network is an important infrastructure of regional social and economic development.In order to predict the regional expressway network traffic volume,economic Cobb-Douglas production function is introduced,and the traffic volume prediction model of the regional highway network is established based on the transport demand function with per capita GDP and population density as the parameters of transportation demand function.The model is based on the simple factor analysis.It can forecast the traffic volume for regional road network and provide a new way for decision-making of the traffic volume of the regional road network. |
