An anonymous reader links to this story at The Stack (based on this translated report) that "The Moscow authorities will begin using the signal from Muscovites' cell-phones in 2015 to research patterns of traffic and points of congestion, with a view to changes in travel infrastructure including roads, the Moscow metro and bus services. The tracking, which appears to opt all users in unilaterally, promises not to identify individual cell-phone numbers, and will use GSM in most cases, but also GPS in more densely-constructed areas of the old city. The system is already in limited use on the roads, but will be extended to pedestrians and subway users in 2015. The city of 11.5 million people has three main cell providers, all of whom cooperate fully with authorities' request for information. A representative of one, Beeline, said: "We prepare reports that detail where our subscribers work, live, move, and other aspects."
