Urban Security 3D

In the project Urban Security 3D, the main focus is on the assessment and improvement of the subjective sense of security among urban dwellers. Structural and spatial factors which influence the subjective perception of safety in urban environments are identified and operationalized. Emphasis is placed on the identification of places that are perceived as dark, out of sight and out of hearing range.

Based on experience from best practice examples and on-site measurements, the identified elements are incorporated into the algorithms that serve as the core of a software-based planning tool. The software can then be applied to existing three-dimensional city models and thus allows an improved security assessment.

For the first time, a software tool that is based on numerical modelling is developed with which security assessments can be made systematically and empirically. The tool helps city planners and security experts to create more security in urban environments and can be used in participative decision processes.
