Transport is central to environmental sustainability and urban livability, yet evidence for planning 15-minute cities (15mC) is fragmented. Policy decisions often depend on case studies that lack generalisability, while detailed transport models capable of capturing behavioural change and system dynamics are too resource-intensive for routine use. This creates a key research gap: How can we provide robust, dynamic evidence to support 15mC planning that is also fast, transferable, and usable by non-experts?
PERSEUS addresses key challenges in sustainable urban mobility planning and decision-making:
- How to reduce or eliminate time- and data-intensive model curation processes, along with bureaucratic procedures within city administrations.
- How to advance beyond proximity-based POI analysis for 15mC planning by incorporating open data and historic traffic data.
- What elements are necessary for user-friendly interfaces enabling municipalities and stakeholders to simulate and compare multiple real-world scenarios.
- How to engage diverse stakeholders with varying expertise in the co-design process.
PERSEUS addresses the key challenges in 15mC planning through the development of Policy-Effect Navigator: a rapid, evidence-based, model-agnostic, and map-based decision-support tool for real-world use. Specifically, the solution:
- Integrates traffic data with sustainable mobility infrastructures, points of interest (POIs), and key performance indicators (KPIs) to identify potential 15mC areas.
- Uses surrogate modelling to simulate policy effects quickly and accurately, without heavy data or time requirements of traditional models.
- Evaluates impacts of mobility and urban interventions across accessibility, environment, economy, and equity dimensions.
Developed through co-creation with planners, consultants, and government agencies:
- The front end features an interactive web-based interface for users of all technical backgrounds to test, visualise, and compare scenario outcomes.
- The back end embeds behavioural insights and system dynamics for model rigour.
- The navigator will be tested in living labs across 12 partner cities in Greece, Germany, Sweden, and Austria, ensuring adaptability to diverse urban contexts.
Scientific Impacts
- Operationalize surrogate-based rapid planning methods for sustainable mobility improvements
- Introduces an integrated potentiality index to identify the most effective and achievable interventions for 15mC planning.
Practical Application
- Delivers a user-friendly, AI-powered interactive planning tool for real-time testing and assessment of 15mC policies.
- Designed to fit seamlessly into everyday workflows of urban mobility planners.
Broader Benefits
- Builds greater capacity among stakeholders to understand and use modelling tools.
- Uses OSM and other standard data to avoid bureaucracy, saving significant time and human resources.
- Supports faster, data-driven decisions within a democratized, climate-aligned urban planning strategy.
- Strengthens support for climate goals, equity, and vibrant public spaces through inclusive, transparent, and data-informed planning.
