Big data firm Inrix is using big data to re-route traffic . . .

“The traditional approach to monitoring traffic involved using road sensors, which are expensive and barely worth installing on minor roads. Inrix uses GPS signals, which each car with a satnav, fleet-tracking device or configured smartphone app provides. Inrix sucks in real-time GPS data from 100m vehicles. This gives a picture of traffic flow in the UK, the US and other nations to within 15 seconds’ accuracy. And there’s more. “We have over 100 sources of data creating trillions of data points”, says Inrix’s general manager of big data Kevin Foreman. These include weather reports, Twitter, event listings, emergency services data, construction works, commercial fleet activity and other sensors.” See More . . .
