The following demos show street models for different cities including the area around TU Munich, Grafing, Tokyo, New York City and Melbourne.
The 3DCityDB Web-Map-Client is a web based front-end for 3D visualization and interactive exploration of semantic 3D city models.

This demo was created from data provided by the Landesbetrieb Geoinformation und Vermessung (LGV) Hamburg. This includes OpenDRIVE data, which was converted to CityGML using the open source tool rtron. Additionally, this demo contains 3D models of buildings, bridge surfaces, vegetation and a terrain model, which are available as open data.
The original OpenDRIVE data was created in the course of the project TAVF using the Train3DBuilder and kindly provided by the LGV.
Munich Lane Model for an area of 2x2 km around TU Munich
The city of Munich is currently gathering data on roads and the streetspace with lane-level accuracy. Test data of this 'Lane Model' is available for an area of 2x2 km around TU Munich. This data is converted to CityGML and then visualized using the 3DCityDB Cesium Web-Map-Client.

Munich Lane Model adapted to 3D for the area around Donnersbergerbrücke and Trappentreutunnel
The Munich Lane Model data is adapted to 3D using elevation data from airborne and mobile mapping laser scanning as well as raster data on digital terrain models (DEM 1m). The resulting 3D model contains TrafficAreas as well as AuxiliaryTrafficAreas on multiple levels on a bridge leading into a tunnel.

Additionally an artificial re-design of the brige was done in the course of a student project and visualized in the following web-client. Note: The bidge design shown in this demo is not planned in reality and was only created in the course of the student project.
More information on this student project can be found here.

Sonnenstrasse Nord
The city of Munich is currently gathering data on roads and the streetspace with lane-level accuracy. Test data of this 'Lane Model' is available for the northern part of the "Sonnenstrasse" in the center of Munich. This data is converted to CityGML and then visualized using the 3DCityDB Cesium Web-Map-Client.
Frankfurter Ring
Beethoven Platz
Sample data of the Munich Lane Model in an area around the "Beethoven Platz" was converted to CityGML and visualized within a Cesium-based web-client.

The same model was used to conduct a solar irradiation analysis and visualize the effect of vegetation on urban heat islands.

Including diving lanes, crosswalks, bike lanes, sidewalks, markings, vegetation and city furniture (traffic signs, traffic lights, lanterns, etc.).
The original OpenDRIVE data was produced by 3D Mapping Solutions GmbH

The traffic sign models were provided by Software-Service John GmbH | VIS-All® 3D

Due to the large number of individual objects in this demo, the web-client might take a moment to load. The Google Chrome web browser is recommended to view this visualization.
Each TrafficArea contains information on function, area in square meter and the IDs of the corresponding OpenDRIVE referenceline (for driving lanes). This includes TrafficAreas with multiple functions such as driving lane, crosswalk or bike lane. Each TrafficArea can belong to multiple OpenDRIVE referencelines. Note that geometries do not overlap (non-redundant).
The image below shows a query of all TrafficAreas beloning to an OpenDRIVE referencline with id = 3124035 (highlighted in yellow).

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) of Japan runs a project called PLATEAU. Within this project, a street in the city of Numazu containing several sections and intersections was modelled in LoD3. This includes individual driving lanes, sidewalks, green areas, markings, city furniture objects and LoD3 buildings. The models are structured according to the international OGC standard CityGML.
The following Web Client was created using the 3DCityDB. More information on how to transfer the CityGML data provided in the PLATEAU project to interactive visualizations can be found here.
Due to the large amount of data a good internet connection is required. In case the web client is not loading properly try to de-select the LoD3 Buildings layer.
The goal of the project tum2twin is to contribute to a collection of different representations of the TUM campus and its surroundings to promote research and development of new methods.
The following demo contains LOD3 Buidling models created from LOD2 Building models and point clouds using the Sketchup CityEditor. A corresponding Road model was created using the software RoadRunner.
All models are provided as open data in the CityGML format and were converted to 3DTiles using Cesium Ion.

This Web-Client was created using CityGML data provided by the city of Tokyo (Project PLATEAU).
Link: Center of Tokyo - Results of a Solar Potential Simulation
The solar potential simulation was conducted for a area in central Tokyo. Each Building contains information on direct, diffuse and global irradiation values in [kwh/m2], as well as a Sky View Factor (SVF). The simulation was done using a tool developed at the TUM Cair of Geoinformatics. Some OuterCeilingSurfaces were disregarded on purpose.
