With the accelerated urbanization，Guangzhou has preliminarily formed an integrated transportation system，which includes a series of highway，railway，waterway and airway. In order to give full play to the various transportations’ capacity potentials and advantages，it is necessary to achieve the integration and optimization between various means of transportation through different levels of traffic hinge，and then form a powerful，efficient and low-cost transportation system. This paper argues that Guangzhou should treat traffic information as a link and regard transportation junctions as crunode which lead the integration between all the means of transportation including railway，highway，waterway，airway，subway，bus，taxi and other transportation means，and establish the three-dimensional and integrated transportation system with the support of all the functional transportation means.
