高速公路与城市化发展的耦合度分析
Coupling analysis on the development of expressway and urbanization

针对高速公路布局与城市化发展之间的互动关系，借鉴物理学中耦合度函数提出高速公路与城市化进程的耦合度计算模型。应用此模型研究京津冀地区城市化发展和高速公路之间耦合的现状。在此基础上，采用人工神经反馈网络模型对未来5年内两者的耦合关系进行预测，得到京津冀地区的未来发展趋势，为今后协调地区高速公路与城市化发展提供量化的决策依据。
Aimed at the interaction between expressway layout and urbanization development and based on the coupling degree function of physics，this essay put forward the calculating model of the coupling degree between the expressway and the urbanization process. This model was used to study the current situation of the coupling between urbanization and the expressway in Beijing-Tianjin-Hebei region. And this essay applied the artificial neural network model to predict the coupling relationship between the two in the next five years. The future development trend of Beijing-Tianjin-Hebei area was obtained, which can provide a quantitative decision basis for the future coordinated development of expressway and urbanization
