What SUM achieved: SUM turned perceived safety from a soft qualitative concern into an exploitable planning asset. The tool produces safety informed routing and accessibility insights and was applied in Munich and Penteli to show how perceived safety shapes route choice and cycling willingness. This behavioural layer strengthens infrastructure and routing decisions elsewhere in the portfolio.

Life beyond SUM: After SUM, the tool can develop along two tracks: open scientific reuse through the MIT licensed repository, and service oriented exploitation through consultancy or eventual API access. It is unusual because it gives cities a structured way to incorporate perceived safety into planning rather than treating it as anecdotal evidence.

Target users: Cities, planners, shared mobility operators, researchers and, later, technology providers.

Main barriers: Data intensity, need for further automation and the absence of a fully developed service wrapper around the model.

Post project actions and owner: NTUA plans continued application and validation in 2026, followed by API and service oriented development thereafter.
