Personalized Subways

In the September issue of Scientific American, the editors asked a number of people about an innovation that would make cities more livable. My answer? Personalized subways:

Transportation innovation is one of the keys to creating a more livable city. And one innovation that has the potential to greatly impact life through transportation is personal rapid transit. Personal rapid transit is essentially a personalized subway system for a city. These systems use pods that can hold a handful of people, carrying them directly from point to point, with no stops and no waiting at stations. Creating an easier way to navigate a city promotes interactions among its inhabitants and, in turn, a more livable, and potentially more productive, city.

Here’s more about personal rapid transit. And the rest of the answers are here.
