A Proposal for an Improved Transportation Model in Citygml

Abstract

<p><strong>Abstract.</strong> CityGML, an OGC standard, is an open data model for virtual 3D city models and includes buildings, roads, terrain, water bodies, etc. While many modules are well-developed (eg buildings, bridges, tunnels), the transportation model is, based on our consultations with various government agencies and municipalities, not sufficient for most transportation applications. We propose in this paper several improvements to the CityGML v2.0 Transportation module, and to the previous efforts for improving it. Our additions are based on the consultations we had, and on the use-cases that were identified. We argue that the following changes are necessary: A) multi-LoD modelling of roads, B) carriageway representation, C) detailed intersection modelling and, D) introducing waterways as a new sub-class.</p>

CityGML 3.0: New Functions Open Up New Applications

“…This information is typically used (and required) in navigation systems and traffic simulations (cf. Ruhdorfer et al 2018;Labetski et al 2018). According to Labetski et al (2018) also Waterway was introduced as new subclass of TransportationSpace.…”

“…Ruhdorfer et al 2018;Labetski et al 2018). According to Labetski et al (2018) also Waterway was introduced as new subclass of TransportationSpace. In addition, the new class Marking allows for adding road markings to the road surface and the classes Hole and HoleSurface can be used to represent, for instance, roadway damages or manholes including their surfaces.…”

The LandInfra standard and its role in solving the BIM-GIS quagmire

“…Devys [17] discussed interoperability, between the RailTopoModel [81] and Land-Infra, for railway infrastructure and proposed a mapping between the two models. Labetski et al [39] analysed the usage of LandInfra as a framework for extending the definition of the LODs for roads in the transportation module of CityGML, but found that the lack of the concept of levels of detail in LandInfra made it irrelevant. [49] also propose to analyse LandInfra in the context of roads but for the purpose of determining limitations in current data standards for road assets and create recommendations towards an improved standard in order to apply SW (Semantic Web) technologies to build a prototype solution for road asset data conflation.…”

Harmonising the OGC Standards for the Built Environment: A CityGML Extension for LandInfra

“…Among those papers, the majority of them discuss the relationship between LandInfra and the ISO 19152 LADM (Land Administration Domain Model) [11][12][13][14][15][16]. There are also several papers examining the applicability of LandInfra for extending the transportation modelling of roads [17] in the context of road asset management [18][19][20], and for the interoperability between the LandInfra and RailTopoModel [21] for railway infrastructure [22]. Others discuss the usability of LandInfra (& InfraGML) in specific use cases, such as in the creation of a tax valuation information model [15], underground utility network modelling [23] and possible alignments [24] with the CityGML Utility Networks ADE [25] and PipelineML [26], environmental acoustic studies [27], and modelling legal interests and legal boundaries [28].…”

“…Within asset management, the maintenance of roads and transportation networks is key to keeping traffic moving smoothly and safely on a daily basis. Road maintenance includes activities such as smoothness control/de-icing, repairs, closures, milestone maintenance and traffic city furniture replacement [17].…”
