  Road networks exist in the form of polylines with attributes within the GIS
databases. Such a representation renders the geographic data impracticable for
3D road traffic simulation. In this work, we propose a method to transform raw
GIS data into a realistic, operational model for real-time road traffic
simulation. For instance, the proposed raw to simulation ready data
transformation is achieved through several curvature estimation,
interpolation/approximation, and clustering schemes. The obtained results show
the performance of our approach and prove its adequacy to real traffic
simulation scenario as can be seen in this video 1 .
