If we focus on sociability as the starting point for design and tapping citizens as the source of innovation, how do we go about crafting a smarter city from the bottom up? An ideal beginning is to leverage the growing array of smart personal devices we all wield and recruit people as the sensors of a city rather than relying only on formal systems embedded into infrastructure.
The traffic function on Google Maps is a good example. Instead of building a costly network of dedicated vehicle sensors along roadways, Google constantly polls a large network of anonymous volunteers whose mobile devices report their up-to-the-minute status, which reveals where traffic is flowing, slowed or stopped.
