Superblocks

Barcelona, Spain.

Barcelona, a city known for its innovative urban design, has implemented a revolutionary strategy to improve the quality of life of its residents: superblocks (superilles in Catalan). More than just an urban development intervention, superblocks represent a paradigm shift: putting people first and reducing the dominance of cars in the heart of the city.

What are superblocks?

Imagine grouping nine traditional blocks into a larger block, where vehicle traffic is limited to the perimeter streets. Inside, the space is transformed into priority zones for pedestrians, bicycles, and public transportation. Superblocks don't eliminate traffic, but rather redistribute it, reducing speeds and creating a safer and more pleasant environment.

Benefits that promote walkability:

  • More space for pedestrians: Sidewalks are widened, seating areas are created, and spaces are freed up for social and cultural activities.

  • Safer streets: Reducing traffic speeds and the number of vehicles reduces accidents and promotes safer mobility for all.

  • Less pollution: Reducing motor traffic contributes to improving air quality and reducing noise pollution.

  • More green areas: Trees are planted, gardens are created, and spaces previously occupied by cars are greened.

  • More vibrant communities: Social interaction is encouraged, local commerce is revitalized, and a sense of belonging is strengthened.

Results

The superblock project began its experimental implementation in 2016 and has since shown promising results. Various impacts have been measured in the areas affected, including:

 

  • Traffic Reduction: In the inner areas of the superblocks, traffic has decreased by 21-26%, creating quieter and safer spaces.

  • Increased Pedestrian Activity: An increase of up to 12% has been observed in the number of people walking and enjoying public spaces.

  • Improved Air Quality: Reductions of up to 30% have been recorded in nitrogen dioxide (NO2), an air pollutant harmful to health.

  • Economic Boost: Local businesses have benefited from the increased pedestrian activity, with an estimated 10% increase in sales in some establishments.

These data, although preliminary, demonstrate the potential of superblocks to transform urban life and build more people-friendly cities.
