abstract: >-
  To facilitate the generation of interactive environments
  for cycling simulation, this project presents a
  Unity-based pipeline for procedural generation of both
  real maps from the OpenStreetMap (OSM) database and
  synthetic maps. The pipeline integrates geospatial data
  parsing, terrain and road network reconstruction, and
  real-time simulation in a single workflow, enabling rapid
  creation of maps without manual modeling or external
  preprocessing. The produced 3D environments preserve key
  infrastructural features relevant to cycling, including
  complex road networks, elevation changes, and low-poly
  buildings. The system supports interactive navigation with
  a controllable bicycle agent via keyboard or VR
  controllers. We have evaluated the approach showing that
  both real-world maps and customized synthetic environments
  could be generated efficiently while maintaining
  simulation performance up to 60 FPS. Identified
  limitations include dependency on OSM data quality,
  elevation resolution, and the current restriction to
  simple building geometries and a limited set of semantic
  infrastructure types, with future work aiming to extend
  support for additional infrastructure types and further
  improve scalability.
