Three years ago, 100 Parisians volunteered to wear a wristband with a sensor in it. The sensors measured air and noise pollution as the wearers made their way around the city, transmitting that data back to an online platform that created a virtual map of the city’s pollution levels, which anyone with an Internet connection could take a look at.

It was simple, elegant, effective — and a peek at the urban future, when “smart cities” will collect data of all kinds (in all kinds of ways) and use it to make themselves better places to live. The Paris wristband project shows how these efforts are already taking place, as urbanites conceive of solutions to their cities’ problems through creative uses of technology. It’s urban resourcefulness at its finest.

But it may not last. The smart-city movement is at a crossroads. With the market projected to be worth $16 billion by the end of the decade, big companies like IBM and Cisco have much grander — and more profitable — ambitions than these small-scale projects. They’re going all-in on smart cities, with designs that supposedly do everything from end traffic jams to prevent disease outbreaks to eliminate litter. “Almost anything — any person, any object, any process or any service, for any organization, large or small — can become digitally aware and networked,” said IBM Chairman Samuel J. Palmisano at the 2010 SmarterCities forum in Shanghai. “Think about the prospect of a trillion connected and instrumented things —cars, appliances, cameras, roadways, pipelines …”

Indeed, the goal of these companies is not just to participate in the evolution of smart cities, but to connect and control virtually everything with massive operating systems that will run these cities in their entirety. “Everybody wants to be the architects of these systems because then you own them forever,” says Greg Lindsay, author of “Aerotropolis” and an urban-technology reporter for Fast Company. “You could say it’s sort of a land grab.”

Which of these futures should smart cities shoot for — the bottom-up model or the top-down version? A few weeks ago, Lindsay and Anthony Townsend of the Institute for the Future debated just that question. It’s easy to feel a knee-jerk reaction against the top-down, evil-corporate-overlord schema, but it has some things going for it. Rio de Janeiro is perhaps the closest thing the world currently has to a top-down smart city. Two years ago, IBM built an enormous, Mission Control-like facility for Rio, from which emergency services, transit, traffic, air quality, weather, contagious disease outbreaks, landslides and just about everything else is now monitored and managed. “Eighty interchangeable digital panels project live video feeds from 450 cameras,” is how the Daily Beast described it, “plus a dizzying array of tricked-out Google Maps of schools and hospitals, car accidents … and close to 10,000 GPS-tracked buses and ambulances.”

It’s an undeniably nimble and efficient method (assuming the system doesn’t crash), and will come in handy when Rio hosts both the Olympics and the World Cup in the next four years. But it also consolidates power in the executive branch and creates an unsettling scope of surveillance. Its greatest novelty, however, may be that the system effectively puts a corporation, IBM, partially at the helm of a city of 6 million people.

“It has something like 70 different city departments under it,” says Lindsay of Rio’s system. “You create this entanglement where IBM almost becomes part of the city government. You couldn’t untangle it if you wanted to.”

Not to mention the fact that IBM is a computer company, not an urban planning consultancy. In his debate with Lindsay, Townsend asserted that the companies vying for smart-city dominance “know nothing about cities.” In fact, he said, despite having one of the biggest smart-city divisions in the IT world, IBM just hired its first urban planner last year. Why so little interest in what makes cities tick? “That’s probably the whole arrogance of the technology culture,” said Lindsay. “I think the software industry sees urban government as having failed.” Their attitude is: “‘We will come into your city and we will fix it.’”
