Concept Project: ASAM OpenDRIVE lite with linked CityGML

Description:

For testing and validation of advanced driver assistant systems and automated driving simulation is used. The complex systems under test do 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 1.8 was published in November 2023. Nevertheless, disadvantages and issues arose, including the following:

  • Simulation settings and road settings became more and more complex and therefore the handling of the data does not scale.
  • More real-world data was introduced. The modeling approach of OpenDRIVE is stretched to its limits.
  • The databases were linked with various other databases for sensor simulation.

Detailed Background:

The standard CityGML issued by the international Geospatial Consortium (OGC) is the most commonly used format for storing, modeling and exchanging semantic 3d environments. 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 using explicit coordinates. 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 to segmenting the street space into individual objects as well as modeling the road (e.g. linear referencing, parametric geometries).

Simply 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 to bridge the gap between the two standards.

The proposal for this concept project is to re-think the road modeling approach incorporating requirements of automotive domain.

  • Use CityGML strength to model a semantic 3d environment
  • Define a compact standard based on OpenDRIVE 1.x to model road logics
  • Define a linkage concept to meet requirements of the whole simulation domain and improve interoperability between GIS and automotive domain
  • Re-use the linkage concept to connect to additional relevant road information

Completion Criteria:

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).
