Other popular GPS mapping apps, like Apple Maps, Waze, Nokia’s HERE maps, and Mapquest, all offer traffic information, but the advantage Google has is the sheer number of people who use it, and the amount of data it has. “It’s not just what [traffic] is right now, but how do we expect it to change over the next hour or two hours,” Amanda Leicht Moore, the lead product manager for Google Maps, said in an interview with Tech Insider. Google Maps also incorporates traffic and incident data, like accident reports, from Waze, the popular navigation app that Google bought for more than $1 billion in 2013. Waze gets its information from users who report things like accidents on the road or traffic jams. Google also gets information from local departments of transportation.
