As society has become more complex and interconnected, so should our ideas about how we build and service cities. As a case in point, new “soft” technologies are already transforming hard infrastructure. Commuter train ridership, for instance, is more attractive when you can log onto a laptop and get in two more hours of work while you ride. Similarly, mobile phones have made hours stuck in traffic more palatable (even as they’ve made traffic more dangerous by distracting drivers). We could build on such practices, subsidizing fiber-optic communications lines to Main Street to encourage the growth of offices in downtowns that languish half-empty while peripheral suburbs boom. Or we could add wi-fi to all forms of public transit, encouraging commuters to get out of their cars and into existing buses and trains. But this is only a start, and we need to be daring. We need to reinvent infrastructure with new technologies.

I’d like to suggest that we embrace a cultural practice that is about as far from Congress and the White House as can be imagined: hacking. In the post-9/11 culture of government paranoia, hacking is tantamount to terrorism, but in the best sense of the word, hacking sets out not to harm other people but to expand our horizons, using systems in ways they were not intended as a means to free information. This is amply shown by the internet’s rapid growth, which stems from its status as an ideal environment for hackers. Anyone with a small investment in access can build new applications and interfaces. Why not open up infrastructure in a similar way? Legislating open access to data in new and existing infrastructure would allow developers to build applications—many of them as yet unforeseen—that would exploit that data to expand our infrastructural possibilities.

Take Google Maps on the iPhone. This service delivers up-to-date information about traffic speeds. Granted, it’s not perfect. Not all routes are covered, the data is too coarse, and sometimes it is unavailable, making real-time routing tricky. Still, I have a good sense of whether I should take the George Washington Bridge or the Holland Tunnel on the odd occasion when I have to drive into the city. With technology like this, there’s no reason why New York’s subway riders can’t be equally enlightened. If the MTA knows where its trains are, we should know too. It’s preposterous to wait forever to get on a local train only to find out—once the doors have closed—that the train is inexplicably going express, right past your stop. Government agencies have such information at their disposal, yet we, the users, don’t. Incredibly, forms of data as basic as subway schedules can still be hard to obtain, often requiring either Google’s muscle or a canny lawyer and a Freedom of Information Act request.
