In the Proceedings of the National Academy of Sciences — the world's most cited general scientific journal — Ford and MIT demonstrated today [Aug. 29, 2016] how a mere six weeks of historical cell phone location data could be nearly instantly analyzed to provide optimal plans for infrastructure development and resource allocation that city planners might take years to sift out.
"The great advantage of our framework is that it learns mobility features from a large number of mobile phone users, without having to ask them directly about their mobility choices. Based on that we create individual models to estimate complete daily trajectories of the vast majority of mobile phone users," professor Marta Gonzalez at MIT told EE Times in an exclusive interview in advance of the announcement today. "Likely, in time, we will see that this brings the comparative advantage of making urban transportation planning faster and smarter, and even allowing to communicate the recommendations directly to the devise users."
By giving EE Times advance notice of its breakthrough analytics, Ford and MIT were probably expecting an article crammed with buzzwords like Big Data, Crowdsourcing and Disruptive Technologies. The significance of their feat, however, is more important than stringing together tech-talk to describe it. City planners today get paid six-figure salaries to provide this caliber of accurate commuter surveys (which they usually farm out to consultancies which charge them seven-figure prices). By feeding Ford and MIT's algorithms the realtime anonymous data already available from cellphone carriers, the years- to even decade-long urban planning cycles are over.
Because most smartphones have not only location data but accelerometer, gyroscope and magnetometer readings, Ford and MIT's algorithms can also determine whether their users are walking, biking, taking mass transit (and
