Three-dimensional city models are essential for analyzing urban areas. While buildings and the terrain are commonly represented, detailed streetspace models have played a minor role so far. This is changing due to increased data availability and requirements or emerging applications. Thus, revised and extended concepts for modelling the streetspace in the context of semantic 3D city models are developed and published in the international OGC standard CityGML 3.0. Corresponding datasets are created from various sources and used for implementing use cases such as web-based visualizations of traffic simulation results or automatically evaluating the service quality of bicycle paths.
