摘要
首先,提出了超级运输网络模型的概念,研究网络模型中虚拟链接的涵义,提出三种虚拟链接的构建方法,它们分别是基于属性的虚链接、基于城市道路子网络模型的虚链接以及基于多尺度表达的虚链接。然后,根据三种虚联接的表现方法,以三种方式构建中国东北地区的超级运输网络模型,并比较三种网络模型的效用。最后,利用超级网络模型检验综合运输政策体系的实施效果。
First of all, we have put torward the model of super transportation network, studied its concept and the mtension ot virtual links in the model and proposed the methods for establishing three different kinds of virtual links, which are virtual links based on attribute, virtual links based on model of sub-network of urban roads and virtual links based on muhi-scale representation. Then according to the manifestation of the three types of links, we've established the super-network transportation model for the northeastern region of China and compared the ef-fectiveness of three different network models. Finally, we have used the super-network model to examine the effect of the implementation of the comprehensive transportation policy system.
