Project Content

For testing and validation of advanced driver assistant systems and automated driving simulation is used. The complex systems under test not only need precise and detailed modeling of the road but also a growing amount of information about the environment, too.
 

Currently ASAM OpenDRIVE is fulfilling the task for the road description quite well, thus it became de-facto standard in automotive domain. The newest version 1.7 was published in August 2021. Nevertheless, disadvantages and issues arose, including the following:
 

  • Simulation settings and road settings became more and more complex
  • More real-world data were introduced.
  • The databases were linked with various other databases for sensor simulation.


The standard CityGML issued by the international Geospatial Consortium (OGC) is the most commonly used format for storing, modelling and exchanging such semantic 3D city models.  Highly accurate geo-referenced, geometric and topological information as well as semantic capabilities are key strengths of CityGML. Different thematic modules are available to cover diverse use cases, including simulations and analyses. The newest version 3.0 of CityGML was published in September 2021 and contains revised and extended concepts for modelling the street space. Compared to OpenDRIVE, CityGML follows a completely different geometric modelling approach based on discrete areas. As general exchange standard for 3d city models CityGML does not cover all requirements for a specific application, which results in some drawbacks regarding the automotive domain. City management applications often require a fragmented view of the traffic area, which does not match a simulation view:
 

  • Semantic concepts differ with respect to their approach on segmenting the street space in individual objects as well as modelling the road (e.g. linear referencing, parametric geometries) 
  • Only including OpenDRIVE into CityGML does not solve the OpenDRIVE issues.


CityGML contains a built-in mechanism for extending the data model of the standard with concepts not originally within its scope called Application Domain Extensions (ADE). This could help in order to bridge the gap between the two standard


The proposal for this concept project is to re-think the road modeling approach incorporating requirements of automotive domain using the Area Concept of the OpenDRIVE concept project to tackle the challenges of the realistic representations of real-world data on a larger scale. The project should come up with a proposal how to combine precise road description of large real world road networks, road infrastructure and furniture together with their complex environment. The concept project will bring together the expertise of both, automotive and city modeling domain to propose an easy and modular solution that is easy to use and extendable by further relevant stakeholders (e.g. traffic or energy management).
