Curitiba's IPPUC planning institute, running since 1965, now operates 'Hipervisor', a real-time cross-department data platform that helps the city anticipate flooding and traffic — a rare case of a 60-year-old institution still updating its data infrastructure.
The Institute of Research and Urban Planning of Curitiba (IPPUC) was created in 1965 to implement and continuously update Curitiba's master plan, making it one of the world's longest-running municipal planning agencies. Since 2007 it has worked alongside Concitiba, a multi-stakeholder city council checking policies against social, economic and environmental goals.
IPPUC's headquarters now houses a control centre for 'Hipervisor', a public data collection and sharing platform that aggregates, processes and distributes real-time information across city departments so officials can anticipate problems such as traffic congestion and the impact of heavy rainfall before they escalate.
Curitiba's continuous six-decade adherence to an evolving master plan is documented by the American Society of Civil Engineers and the Transportation Research Board, alongside city-level indicators such as 52 square metres of green space per resident across a population of 1.7 million (3.5 million metropolitan).
Direct, isolated performance metrics for Hipervisor itself are limited in public sources, which C-NAPSE evaluators reflect in the evidence score even while crediting the institution's exceptional longevity and cross-department integration.
