摘要
辽宁省大连市金普新区经济发展转型升级加快,引领示范作用持续强化,对综合交通运输发展提出了新要求。在分析大连金普新区公路网现状特征的基础上,分析金普新区公路网存在的问题。采用连通度法和弹性系数法,预测金普新区公路网规模,避免了单一预测方法在数据应用中出现的偏差;采用分层布局法对金普新区公路网布局结构进行分析研究,确定了金普新区公路网布局结构,该布局的总里程符合预测模型的计算结果。研究可为类似项目提供参考。
Dalian Jinpu new area in Liaoning province has accelerated its economic transformation and upgrading,continuously strengthened its leading and demonstration role,and put forward new requirements for the development of comprehensive transportation.On the basis of analyzing the current characteristics of the highway network in Dalian Jinpu new area,the problems that exist in the highway network of Jinpu new area are analyzed.The scale of the highway network in Jinpu new area is predicted by using the connectivity method and elasticity coefficient method,so as to avoid the bias in data application using a single prediction method;the hierarchical layout method is used to analyze and study the layout structure of the highway network in Jinpu new area,and the layout structure of the highway network in Jinpu new area is determined.The total mileage of this layout conforms to the calculation results of the prediction model.The research can provide reference for similar projects.
