Perceived health, wellbeing and equity impacts of Barcelona’s Green Axes: a rapid qualitative study of residents and public-space users
This rapid qualitative study of Barcelona's Green Axes reveals that while residents perceive significant improvements in tranquility, social interaction, and thermal comfort—particularly among older adults, children, and caregivers—concerns regarding residual traffic, micromobility safety, poor maintenance, and gentrification explain the disconnect between observed public space usage and the intervention's intended health and equity benefits.

Cities are more than just collections of buildings and roads; they are complex environments that directly shape the health of the people who live within them. The air we breathe, the noise that surrounds us, and the availability of green spaces are fundamental factors that determine whether a community thrives or struggles. When traffic is heavy, it brings pollution and noise that can harm our lungs and hearts, while a lack of places to walk or sit can isolate us from our neighbors. Urban planners and public health experts have long understood that changing the physical layout of a city—by slowing down cars or planting more trees—can improve these conditions. However, knowing that a design looks good on a map is different from knowing how it feels to live there. The true test of any urban change is whether the people using the space actually feel safer, healthier, and more connected, and whether these benefits reach everyone or only a few.
In Barcelona, a city known for its dense streets and high traffic, researchers recently investigated a major experiment in urban design called the "Green Corridors." This project transformed a long, straight stretch of the city into a shared space where cars are limited to a very slow speed of 10 kilometers per hour, and the ground is paved with stone rather than asphalt to create a single, flat level for everyone. The goal was to create a linear park where people could walk, play, and rest without the danger and noise of fast-moving traffic. To understand if this change truly worked, a team of researchers from the Barcelona Public Health Agency spent time in the area in March 2024. They did not just count cars or measure air quality; they spoke directly with 64 people of different ages and genders who lived, worked, or walked through the new corridor. By listening to their stories and watching how they used the space, the team uncovered a nuanced picture of how this intervention affected daily life.
The researchers found that for many residents, the transformation brought a profound sense of relief and well-being. People reported that the area felt much quieter during the day, and the addition of new trees and plants made the street feel inviting and cool, especially during hot weather. Older adults and parents with young children were among the biggest beneficiaries. Grandparents found they could sit on the new benches and chat with neighbors without shouting over traffic, while parents felt they could let their children play and walk to school with a greater sense of freedom. The space encouraged people to linger rather than just pass through; families gathered for meals on the street, and people walked more often because the route felt pleasant and safe. This shift from a place of transit to a place of staying created new social rituals, regenerating a sense of community that had been lost when the street was dominated by cars.
However, the experience was not uniformly positive, and the researchers discovered that the design created specific challenges that were not immediately obvious from a distance. While the objective data showed that the street was cleaner and safer, some residents, particularly older women and parents, expressed a lingering feeling of unease. Because the street was designed as a single flat surface without curbs to separate pedestrians from vehicles, people felt they had to remain constantly alert. They described a "false sense of security" where the absence of physical barriers meant that a car, a delivery van, or a scooter could appear suddenly next to where they were sitting. This ambiguity made some vulnerable groups feel exposed, even though the cars were moving slowly. Additionally, while the daytime traffic noise dropped significantly, the noise from nightlife and people gathering in the evenings remained a concern for some residents, and the vegetation, though increased, was sometimes seen as poorly maintained or lacking in variety.
The study also highlighted how these changes affected different groups in different ways, revealing that the benefits of such projects are not shared equally. Women who were responsible for caring for children or elderly family members found the space particularly valuable because it made their daily tasks easier and provided a place to socialize while they cared for others. In contrast, some long-term residents worried that the improvements were driving up property values and rents, potentially pushing out the very neighbors who had lived there for decades. There were also fears that the area was becoming too focused on tourists, which could weaken the local social fabric. The researchers noted that while the physical environment had improved, the success of the project depended heavily on how well the city managed the space day-to-day, including keeping the area clean, enforcing rules about parking and speed, and ensuring that the new greenery was cared for properly.
Ultimately, this research suggests that building a greener, quieter street is only the first step. The real health benefits depend on whether the design feels safe and welcoming to the most vulnerable users, from the elderly to the very young. The study showed that while the physical improvements were real, the perception of safety and the quality of the social environment were just as important. For the project to succeed in the long run, the city must address the concerns about shared space and maintenance, and ensure that the neighborhood remains affordable and inclusive. By listening to the people who actually live there, planners can learn that a successful urban space is not just about removing cars or adding trees, but about creating a place where everyone feels they belong and can move through the world with confidence.
