摘要
铁路网适宜规模的确定可为研究和制定铁路网规划提供依据。在分析铁路网建设规模的影响因素、铁路网规模常用预测方法的基础上,通过自变量的选择、模型的建立和模型参数的标定和检验,建立以铁路网密度和人口密度、人均GDP的关系模型为多元指数模型。通过以陕西省铁路网为例进行的分析验证,认为该方法适用于铁路网规模测算。
The confirmation of railway network with proper scale will provide a basis for studying and making plans for railway network. Grounded on the analysis of influence factors of railway network construction scale and general predicting method of railway network scale, by selecting independent variables, establishing models and calibrating and examining model parameters, the relational model based on density of railway network and population and GDP per capita is built as the multi-element index model. Railway network in Shaanxi province is analyzed and verified, and the results show that the method is suitable for the prediction of railway network scale.
