Beyond OSM – Alternative Data Sources and Approaches Enhancing Generation of Road Networks for Traffic and Driving Simulations

Kurzfassung

Often OpenStreetMap data is used in the creation of the anderlying road networks for traffic simulations; sometimes it can be enriched with navigation data. Due to the fact that traffic simulation plays a growing role for the development of driver assistance and automation systems more detailed road networks are necessary because traffic simulations are coupled to driving simulators. This detailed information on lane-level and road infrastructure is not available in OSM or navigation data or modelled in an inappropriate way. This paper will discuss alternative data sources like cadastral or mobile mapping data, their advantages and disadvantages compared to OSM and navigation data and will give an idea on how inappropriate data could be improved. We will show approaches of how to fuse this data to a road network using the OpenDRIVE format resulting in a suitable output for the use in traffic and driving simulations.
