City Know-hows
Walking is one of the simplest ways to support health, but people only walk when streets feel comfortable, safe, and attractive. Our study shows that small design choices at the street level can strongly shape walkability, and that immersive virtual reality can help cities test these choices before making expensive changes.

The problem
Many cities want to encourage walking, but the design of everyday streets often makes this difficult. Poor sidewalks, weak pedestrian comfort, traffic pressure, and low-quality public spaces can discourage people from walking even when destinations are close. In practice, these small street-level features are often overlooked, even though they have a direct effect on how people experience the city.
What we did and why
We used immersive virtual reality to examine how people respond to different micro-scale street design features in a neighborhood in Tehran. This method allowed us to test street conditions in a controlled way without changing the real street. We used it because virtual reality can help planners understand how people may perceive and react to design choices before those choices are implemented in the real world.
Our study’s contribution
The study shows that walkability is shaped not only by major infrastructure, but also by small design details such as greenery, seating, enclosure, and the quality of pedestrian space. It also shows that virtual reality can be a useful tool for evaluating these features in a realistic but controlled environment. This makes it possible to compare design options more safely and efficiently than relying on field observation alone.
Impacts for city policy and practice
For planners and decision-makers, the main lesson is that improving walkability does not always require large-scale redevelopment.
Small but visible changes to streets can make a meaningful difference in how people feel about walking. Cities should use digital testing tools more often, design streets according to local conditions, and pay more attention to the everyday quality of pedestrian spaces. Virtual reality can also support better early-stage decision-making by showing which design options are likely to work best before construction begins.

Intertwining play and placemaking (‘PlaysMaking’) in Cork city has inspired positive changes in the spaces, places and lives of citizens. The barriers of high car dependence and a history of resistance to pedestrianisation policies in the city were overturned by levering play to temporarily pedestrianise areas in the city. Community led PlaysMaking in Cork City has secured the permanent pedestrianisation of public roads, creating inclusive recreational spaces and led to the creation of dedicated public spaces for popup events and playful cultural trails.
Using a qualitative approach, we examined health vulnerabilities and community strategies in response to climate crisis conditions, involving 22 residents from the Toma Nuevo Amanecer informal settlement. Primary data was collected through ethnography, a focus group, and semi-structured in-depth interviews. This approach aimed to understand how extreme weather events, such as landslides, heatwaves, floods, fires, and air pollution, impact migrant communities and their coping strategies.
