Combined Modelling of Multiple Transportation Infrastructure Within 3d City Models and Its Implementation in Citygml 3.0

Abstract: Abstract. The development of digital urban twins has led to efforts of multiple cities to gather detailed and highly accurate data on many parts of urban environments, including road and railway infrastructure as well as areas used by pedestrians. This paper presents concepts for representing and segmenting this data semantically, geometrically and topologically ensuring usability for various multimodal applications in the context of digital 3D city models. First, methods for modelling multiple transportation … Show more

“…Furthermore, authors in [33] discuss that the data must be easily accessible through an advanced geoportal for multiple users in a presentation of 3D spatial GIS models. The authors of [38] mention DT 3D modeling standards in the context of smart cities such as geographic data files (GDFs), CityGML, OpenDRIVE and Open Geospatial Consortium (OGC) standards such as LandInfra. Currently, research scientists are being left behind by several industrial leaders which are moving towards detailed simulation modeling without considering the true and powerful research questions about the capability of such systems powered by big data and AI, which represents a significant gap in some cases that needs to be filled.…”

“…Transportation systems, especially within big cities, not only include streets but also contain other transportation infrastructure, such as railways, trams, or waterways and canals. These multimodal transportation types often interact with each other and in many cases even share identical spaces in the city [6]. Level crossings of streets and railways or tramways within a road, for example, are part of the streetspace.…”

“…Usage of XLinks to implement object linking to avoid redundant representations is explained in more detail in the CityGML specification document [29]. Beil and Kolbe [6] demonstrate this concept for multiple transportation types, including a level crossing shared by a Road and a Railway object simultaneously. In the example in Figure 3a, Intersections are reduced to the smallest area used by different Roads.…”
