Summary/Abstract: This paper examines 3D visualization of traffic offences based on open data sources at the city level. Most of the existing studies and applications focus on 3D visualization of qualitative data. For this reason, this paper concentrates on 3D visualization methods for quantitative data. The possibilities of creating 3D dot maps, statistical surfaces, graduated 3D symbols and prism maps and their effective use was studied. A pilot web application visualizing crime statistics was developed for verifying the applicability of selected 3D cartographic methods and the feasibility of open source technologies for crime mapping. 3D visualizations of selected traffic offences registered and solved by municipal police (different traffic offences types) are available in a pilot application for the city of Brno (Czech Republic). The design and implementation of map components, interactive functionality, limitations and opportunities for future development are also discussed.
