Bij FAQ:
Where does the traffic data come from?This up-to-date information is bought in from an external service provider.
The data is compiled using anonymous movement profiles of mobile
phones, smart phones with online navigation apps
and online navigation
systems. A certain number of mobile phones and navigation devices must transmit data in order for the traffic situation to be analysed. Only then can a meaningful picture of the traffic situation be obtained. Information from road sensors, traffic control centres and accident reports is also used.
