When cities forget about pedestrians, big data and technology can serve as a friendly reminder

Paraisópolis, a nationally famous slum area in São Paulo, Brazil, is one of those bustling communities where everything happens. Despite being located in the middle of the city, it managed, unlike other poor slum areas, not to be reallocated to make room for more expensive housing or public infrastructure. The area boasts vibrant community life, with more than 40 active NGOs covering issues that range from waste management and health to ballet and cooking. Recently, the area also benefited from several community upgrading programs. In particular, investments in local roads have facilitated truck access to the community, bringing in large and small retailers, and generating lively economic activity along with job opportunities for local residents.

As we continue our efforts to increase awareness around on-foot mobility (see previous blog), today, I would like to highlight a project we developed for Paraisópolis.

While most of the community has access to basic services and there are opportunities for professional enhancement and cultural activities, mobility and access to jobs remains a challenge. The current inequitable distribution of public space in the community prioritizes private cars versus transit and non-motorized transport. This contributes to severe congestion and reduced transit travel speed; buses had to be reallocated to neighboring streets because they were always stuck in traffic. Pedestrians are always at danger of being hit by a vehicle or falling on the barely-existent sidewalks, and emergency vehicles have no chance of getting into the community if needed. For example, in the last year there were three fire events—a common hazard in such communities—affecting hundreds of homes, yet the emergency trucks could not come in to respond on time because of cars blocking the passage.

Sustainable cities, two related challenges: high quality mobility on foot and efficient urban logistics (Part I) ​

Walking is the cheapest, most non-polluting, and possibly healthiest mode of transport. And dense cities seem to be a pre-existing condition for enabling us to meet our daily walking needs, along with diversified land uses, typically called “mixed-use development”. Densification and “mixed-use development” are currently seen as a strategy for designing sustainable cities, and many high-quality mobility plans, which consider the interactions between land use and transport, also pursue this type of urban development.

But densification and “mixed-use development” present (at least) two challenges. The first is how to provide quality pedestrian infrastructure that encourages non-motorized mode choices. The second is how to efficiently deliver the large quantities of goods required in these dense cities. These were the themes of successful seminars recently held in Sao Paulo, Brazil, thanks to a World Bank’s Global Environmental Facility grant.
The “mobility by foot” seminar was a four-day learning event on pedestrian mobility organized by Brazil’s Associação Nacional de Transportes Públicos.  In Brazil, as in most cities in Latin America, around 35% of people’s daily trips are on foot, and there is evidence that this number is underestimated given the limitations of current data collection methods. Given the priority in reducing the impact of our carbon “footprint” (or “carprint”), governments need more evidence and incentives to move the sustainability agenda forward.

The Future of Driving and Finding the Right Incentives for Behavior Change

What would blogs be good for if it were not for their intent on steering a bit of controversy?
So here it is… I do not believe that behavior change interventions can effect lasting change in people’s travel patterns unless real choices are available to them within the local context.

“What do you people have against pedestrians and bicycles?”

It doesn’t happen very often. Thank goodness. But there are times, very rare  times, when in our work, we experience a kind of mid-life crisis, when some external event sparks the realization that we have been traveling down a decision-path for so long, we’ve lost sight of something very important – when we stop and say, how did we get here?

It happened last month -- in Weihai, China’s Shandong Province, where we are working with the municipal government on the development of the city’s first Bus Rapid Transit (BRT) lines.
