City-wide lane model: lane-exact representation of the road space

Result of the project Digital Twin Munich as part of the funding guideline "Digitalization of Municipal Transport Systems" by the Federal Ministry of Transport and Digital Infrastructure.

lane-level model of the road network between central station, the Lenbachplatz and the Sophienstraße.

The lane model contains the entire road system of Munich in a simulation-enabled data structure.

The lane model depicts Munich's public roads including lanes and turning options, in great detail based on the Road2Simulation guidelines of the DLR (German Aerospace Center). In addition to the geometry, the data contains semantic information such as the type of use per lane, the maximum speed or the turning options at intersections. The structure is based on common data standards and StVO requirements and considers all possible road users. The lane model is based on the city's geospatial data and is compatible with existing data sets. In addition to the Digital Twin Munich datasets, other datasets such as traffic signal heads are also included. A wide range of road traffic applications can be covered due to the level of detail and the size of the dataset.

Contribution to the digitalization of municipal transport systems

The mathematical simulation capability of the data structure provides the basis for microscopic traffic simulations. Derived interface formats, such as OpenDRIVE®, can also be used as HD maps for automated vehicles. Furthermore, the routable node-edge network enables reachability analyses. The Lane model is used to generate CityGML data and 3D scenes. The data model thus provides a useful basis for urban planning and public participation.

Contribution to air pollution control / clean air in the City of Munich

Due to the mathematical simulation capability of the data, the modeling of actual and planned states in relation to traffic flow is a core application of the lane model. For example, the quality of bicycle lanes can be derived from the database. Among other things, the traffic simulations support the calculation of the effects of conversion measures on air pollution.

Perspective of the action

The modularity of the attribute and geometry structure enables flexible conversion to different standards and use in a wide range of software solutions. The detailed scope of the data allows the lane model to increase the effectiveness and depth of detail of city administrations in a wide variety of projects relating to road space.
