I've heard stories, guesses, and claims that the current traffic data shown on google maps is potentially aggregated from smartphone GPS and accelerometer readings on android phones or though their Google apps. It's crazy and amazing to just think about it.
- on_and_off 9y agoI always thought this was officially a feature of maps ? I worked for a couple of years in a valley with only 2 access points. Quite often, when it is time to go back home, the trafic would be jammed. I activated Google Now (or at least I think it was already called that way ?) and without fail it would warn me that there is no point in leaving the building right now since everything was jammed. The same info was visible on maps.
