Transport policy is no longer just a top-down process. The rise of co-creation approaches, supported by data visualisations, allows policymakers, citizens, and stakeholders to collaboratively design, test, and improve urban mobility solutions.

In practice, co-creation means engaging users at multiple stages: from identifying transport problems, proposing interventions, to evaluating outcomes. For example, dashboards like the Pilsen traffic map or the Issy Mobility Dashboard provide real-time traffic data, accident statistics, and scenario modelling, enabling stakeholders to visualise the impact of interventions before they are implemented.

Such tools help identify traffic hotspots, congestion patterns, and safety risks, making it easier for both experts and non-experts to participate meaningfully in policy discussions. Co-creation also improves transparency and trust, as citizens can see the evidence behind decisions and suggest improvements.

Challenges remain, including data literacy, access to accurate data, and ethical concerns, but when combined with structured engagement processes, co-creation can lead to more effective, equitable, and sustainable transport policies.

In conclusion, transport policy co-creation is most effective when supported by interactive visualisations, stakeholder collaboration, and iterative feedback, allowing cities to respond dynamically to mobility needs.
