Due to steadily growing volume of traffic, using existing transport routes must be optimized. In doing
so traffic simulations are a vital tool. As input data detailed information about the transport system
is primarily required. Generating and adding such kind of data is currently a time-consuming act.
As database for various types of analysis and simulations semantic 3D city models recently gained
importance. Apart from semantic data they provide geometry, appearance and topologic informations
on city objects. This Master’s Thesis examines on theoretical basis, which information can be
supplied by city models for traffic simulation applications. A coupling of traffic simulation with 3D city
models is done at model level and resultant potentials as challenges are discussed. Following theoretical
considerations a concept for an automatic derivation of road networks for the traffic simulation
Vissim from city models in CityGML format is developed. Another concept deals with the visualization
of dynamic traffic simulation results in 3D city models. Both are prototypical implemented in the
enviroment of the 3DCityDB. An evaluation is carried out on basis of two example datasets. The
visualization of simulation results utilizes Google Earth and the 3D Web Map Client, a web-based
viewer for 3DCityDB based on Cesium.
