Where do you get your traffic data from? Which devices?

Since 2008 we have been collecting anonymous consumer-driven GPS based measurements. We receive signals from anonymous TomTom connected car in-dash navigation systems, portable navigation devices and anonymous GPS-equipped mobile phones.

TomTom has over 600 million connected devices in use globally. This community generates over 3.5 billion kilometers of GPS measurements every single day and to date TomTom has amassed trillions of GPS measurements in over 80 countries.
