New Projects Use Phone Data To Track Big Cities' Mass Transit Use

An anonymous reader points out a New York Times article about a traffic analysis program that "'works by taking note of which cellphone tower a phone is communicating with. It then looks for disruptions in service followed by significant changes in location. If a phone located near Times Square suddenly loses service and reconnects at Prince Street and Broadway 15 minutes later, then it has almost certainly traveled there using the N or R trains.' In another interesting twist, the article briefly notes, 'The system will also include an experiment that uses phones' microphones to sense when riders are on buses.'" The article also mentions a similar project to track buses and trains in Los Angeles.

    So who all gets access to this information about which cellphone is connecting to which tower, and what rights did I give to this person/entity to use it for stuff like this?

      More worryingly, how did they get access to the noise level from my cell phone's microphone? I don't buy the need for them to know where I am on the bus.
