Nossa Cidade (“Our City”), from TheCityFix Brasil, explores critical questions for building more sustainable cities. Every month features a new theme. Leaning on the expertise of researchers and specialists at EMBARQ Brasil, the series will feature in depth articles on urban planning, sustainable mobility, gender, resilience, and other key themes for sparking more sustainable development in our cities.
Walking is the most democratic way to get around. It is the oldest mode of transport, the most common in the world, it’s free, and it may even help you burn a few calories.
Nevertheless, people are walking less and less. As cities have become more sprawled, highways have replaced sidewalks, creating significant obstacles to walking safely. Sidewalks with broken concrete, narrow widths, and illegally parked vehicles on them are further evidence that walking has is slowly being suffocated by other modes of transport that are less healthy for both people and cities.
We need a shift back to pedestrian-friendly streets. Enhancing the quality of city sidewalks not only attracts more pedestrians, but also helps to create enjoyable public spaces where people want to spend their time.
While they’re decreasing in number, these places do exist already. Living sidewalks can be found in many cities in Brazil and around the world where city leaders have made active transport a priority. Instead of just paving a small strip along broad avenues dominated by automobiles, these cities have decided to enrich their walkable public spaces, emphasizing interaction between people.
To support make walking both accessible and safe, sidewalks should be constructed with these eight complementary and interconnected principles in mind. Together, they not only make for vibrant sidewalks, but contribute directly to the development of active and healthy cities.
Meet the eight principles of the sidewalk:
1. Proper sizing
Sidewalks are made of up three zones: the free zone, where people actually walk; the service zone, where street furniture like benches or trashcans are located; and the transition zone, which gives those on the sidewalk access to buildings lining the street. Understanding the relationship between these components is key for designing appropriately sized sidewalks.

2. Quality surfaces
The material used to construct sidewalks needs to be consistent, firm, stable and slip-resistant. In order to ensure that a sidewalk functions properly, designers must be aware of how the sidewalk is being constructed and the quality of the handiwork.

3. Efficient drainage
Waterlogged streets, paths, or sidewalks are unsuitable for walking. Sidewalks that accumulate water become useless, as pedestrians will likely end up diverting their route through car-filled roads, risking their safety.

4. Universal accessibility
The sidewalk, as a public space, should be accessible to a wide spectrum of users—including those with limited mobility. This means designing spaces that serve those in wheelchairs, on crutches, pregnant women, the elderly, and others with special mobility needs. Listing out the different potential users and their mobility limitations during the design process can help ensure the final product will meet the needs of all pedestrians.

5. Secure connections
Pedestrians often transition to other modes of public transport, and need to be able to safely access stations. It’s important that sidewalks are connected and integrated within larger transport networks.

6. Attractive spaces
Streets are a fundamental part of the urban environment. Sidewalks can play an important role in making the urban experience more enjoyable. Interesting, vibrant sidewalks that can captivate people and make walking more attractive will ultimately facilitate more physical activity while reducing traffic congestion.

7. Permanent security
Day or night, weekday or weekend, sidewalks are always open for us. However, there are fewer people out on foot during certain times of the day and week, leading to potentially unsafe situations given the lack of friendly eyes on the street. Adopting strategies to positively influence safety and security can further encourage walking and help all city dwellers feel more at home in their city.

8. Clear signage
Just like drivers of motor vehicles, pedestrians need clear information so that they can both orient themselves in the city and understand the rules and guidelines of particular sidewalks.
