How does the concept of « walkability » influence urban planning and health outcomes?

In an era where the public health sector is increasingly intertwined with urban planning, a concept has emerged that has had a significant impact on our cities and health: walkability. The idea behind walkability is simple yet revolutionary: designing neighborhoods and public spaces to encourage walking as a form of physical activity. This article will delve into the multifaceted world of walkability, discussing its influence on urban planning and health outcomes, as well as its potential as a tool to shape our cities and health for the better.

The Concept of Walkability

Before we can fully appreciate the impact walkability has on urban planning and health, it’s important to understand what exactly it means. The term "walkability" refers to how conducive an environment or neighborhood is to walking. It reflects the design of a locale and its features, such as the proximity of homes to amenities, the presence of safe and well-lit sidewalks, and the availability of public transport.

For you, as residents of your respective cities, walkability can mean the difference between a quick, enjoyable walk to the local shops, or a long, unsafe voyage across disjointed sidewalks and busy roads. More than a mere urban design principle, walkability is about creating neighborhoods that prioritize people over cars and foster a vibrant social life.

Walkability and Urban Planning

One of the fields most affected by the explosion of interest in walkability is urban planning. The concept of walkability has challenged conventional car-centric urban designs and has encouraged planners to put pedestrians at the heart of their schemes.

Walkability has proven to be an effective tool in reshaping our urban environment, leading to the revitalization of public spaces and the enhancement of public transport systems. Planners are now adopting strategies such as ‘complete streets’ – streets designed to accommodate all users, including pedestrians, cyclists, motorists, and transit riders – to increase the walkability of neighborhoods.

One study conducted by scholars at the University of California, Berkeley, published in the journal of Urban Studies (DOI: 10.1177/0042098015578530), found that urban areas with high walkability scores had higher levels of social interaction, community engagement, and economic activity.

Walkability and Health

Walkability isn’t just about creating beautiful, vibrant cities. It’s also about promoting health. Walking is a form of physical activity that is free, requires no special equipment, and can be easily incorporated into daily life.

Numerous studies have shown a clear link between walkability and health outcomes. A review published in the American Journal of Public Health (DOI: 10.2105/AJPH.2009.178002) revealed that individuals living in neighborhoods with high walkability scores were more likely to meet the recommended levels of physical activity and were less likely to be overweight or obese.

Moreover, walkable neighborhoods aren’t just beneficial for physical health. They also have positive effects on mental health. A study published in the Journal of Urban Health (DOI: 10.1007/s11524-012-9749-9) found that people living in walkable neighborhoods had lower levels of stress and depression.

Making Cities Walkable

So, how can we make our cities more walkable? One approach is to focus on the "five D’s" of walkability: density, diversity, design, destination accessibility, and distance to transit.

Increasing density means creating more homes and businesses in a given area, making it easier for you to walk from one place to another. Diversity, on the other hand, involves mixing different types of buildings and uses, from residential to commercial, so that you can access a wide range of services within walking distance.

Good design is vital too. This includes creating safe, appealing, and well-lit sidewalks, minimizing the number of driveways that cross sidewalks, and ensuring that buildings engage with the street. Destination accessibility is about ensuring that common destinations, such as schools, parks, and shops, are within walking distance. Lastly, distance to transit emphasizes the importance of having public transport options close to homes and workplaces.

The Future of Walkability

With the rise of smart cities and the increasing importance of sustainable development, walkability is likely to continue influencing urban planning in the years to come. The concept has already been embraced by many cities around the world, with plans and projects aimed at making urban areas more pedestrian-friendly.

But there’s more to walkability than simply encouraging people to walk more. Walkability is about creating cities that are not just liveable, but loveable. It’s about crafting neighborhoods that are vibrant, diverse, and socially engaging, where the physical environment promotes health and wellbeing, and where the public realm is truly public.

While walkability is undoubtedly a powerful tool in shaping our urban environment and health outcomes, it’s not the only one. As we move forward, it’s crucial to continue exploring and implementing a broad range of strategies to create healthier, more sustainable, and more equitable cities.

In other words, walkability is an important piece of the puzzle, but it’s not the whole picture. As urban dwellers and beneficiaries of these changes, it’s important for you to understand that creating healthier and more sustainable cities requires a holistic approach, that includes everything from urban design to public policy, from transport planning to community engagement.

Revitalizing Cities through Walkable Design

An important aspect of walkability is the positive impact it has on the revitalization of our cities. Urban planners are rethinking their strategies and incorporating walkability into their designs, and the results are clear to see. Cities that have embraced walkability show increased vibrancy, social interaction, and economic activity.

A key element of making cities more walkable is the concept of ‘complete streets’. These streets are designed to accommodate all users – pedestrians, cyclists, motorists, and transit riders. They are safe and accessible, encouraging people to leave their cars at home and walk, cycle, or take public transport.

Research supports the benefits of walkability in urban design. A study conducted at the University of California, Berkeley, and published in the journal Urban Studies (DOI: 10.1177/0042098015578530) found that urban areas with high walkability scores had higher levels of social interaction, community engagement, and economic activity.

Addressing the "five D’s" of walkability – density, diversity, design, destination accessibility, and distance to transit – can further enhance the walkability of a city. This involves increasing the density of homes and businesses, diversifying the types of buildings and their uses, designing safe and appealing sidewalks, ensuring common destinations are within walking distance, and having public transport options close by.

Walkability: A Path to Improved Health

Beyond the aesthetic and social benefits, walkability also contributes significantly to public health outcomes. Regular physical activity, such as walking, is known to have numerous health benefits. It can help maintain a healthy weight, reduce the risk of heart disease and stroke, improve mental health, and increase lifespan.

Walkability encourages physical activity as part of daily life. Individuals living in neighborhoods with high walkability scores are more likely to meet the recommended levels of physical activity and are less likely to be overweight or obese, according to a review published in the American Journal of Public Health (DOI: 10.2105/AJPH.2009.178002).

Apart from physical health, walkable neighborhoods also contribute to better mental health. A study published in the Journal of Urban Health (DOI: 10.1007/s11524-012-9749-9) found that people living in walkable neighborhoods had lower levels of stress and depression.

Conclusion: The Way Forward

Walkability holds significant promise for the future of urban planning and public health. As our cities continue to grow and evolve, the concept of walkability offers a template for creating environments that promote health, wellbeing, and community engagement.

However, it’s important to remember that walkability is just one piece of the puzzle. Creating healthier, more sustainable cities requires a holistic approach, encompassing everything from urban design to public policy, from transport planning to community engagement.

As the beneficiaries of these changes, we all have a role to play in advocating for and supporting policies that promote walkability. By doing so, we can help shape our cities into places that are not just livable, but are also loveable – places that prioritize the health and wellbeing of their residents, foster a vibrant social life, and contribute to a more sustainable future.
