Abstract
Geographic information systems (GIS) are frequently used to represent traffic information in the form of shapefiles. Compared to GIS, building information modeling (BIM) provides extra useful features that can be utilized to extend and improve the functionality of the GIS model. This study was conducted to convert an existing GIS traffic data system to a more robust BIM-based model for traffic data management. In order to achieve the model interaction from GIS to BIM, a visual programming tool, Dynamo, was utilized to transfer the shapes and attributes of the shapefiles. This paper presents an innovative and automatic interaction method for the model conversion from a GIS model to a BIM platform. The traffic model interaction from GIS to BIM is described through an example with a local area traffic database. It is expected that the transformed BIM model can be used for comprehensive road traffic information management.
