Rail transit is an important urban infrastructure,and its digital development is driving changes in many fields in China's urban governance work.Taking into account the characteristics of rail transit assets,e.g.multiple types,wide distribution,and long management cycles,etc.,this article analyzes the current situation of Shanghai rail transit asset data management,including insufficient visualization functions and mismatched fixed asset data,and clarifies the digital twin requirements and applications for asset management.Based on the BIM model,the general idea of the digital twin application of asset management from the data layer,application layer,platform layer,and display layer,is proposed,which is applied to fixed asset mobile inventory,visual inventory and other businesses.Moreover,the paper further explores the management of rail transit real estate resources and strengthens the dynamic management of housing inventories and the information visualization of housing and land information by using a GIS system,finally,a comprehensive integration of GIS data and BIM data is realized,therefore the rail transit asset digitization management is greatly improved.
