The information management platform of transportation infrastructure construction based on GIS + BIM integration is an innovative digital solution, and an integration method of multi-source heterogeneous information for GIS and BIM is proposed. This method is based on the simultaneous thinning of BIM model and attributes, as well as the classification of homogeneous components, in order to adapt to the characteristics of GIS fast and large breadth, establish the interactive query of GIS and BIM, through the application of big data and cloud computing technology, information integration, the establishment of visual digital model. The combined sensing technology and computer vision realize all-round control, so as to further provide problem analysis and solutions, and verify and evaluate in practice, which provides an important reference for the improvement of transportation infrastructure construction.
