As part of the REMEDIO project, a participative process has been developed in order to face the urban redesign of one of the principal roads of Thessaloniki, following the general SUMP concepts. The redesign of this important urban axis of the city was a response to the congestion issues and high traffic affecting quality of life and health of users, workers and neighbours. The vision and objectives were developed thanks to public consultation to record stakeholders’ and citizens’ opinions and technical processing with relevant experts. Active involvement of stakeholders in planning helped create ownership of the solution.
