Data Behind Junction Analytics

When traffic lights aren’t timed right, it creates delays that frustrate drivers, impact the safety and increase congestion. TomTom Junction Analytics helps road authorities, traffic managers and engineers optimize traffic light performance with an easy-to-use API and companion web app.

TomTom gathers real-time Floating Car Data (FCD) by combining measurements of existing infrastructure with signals from anonymous TomTom (connected) GPS devices, connected cars, and anonymous GPS-equipped mobile phones. The trips come from completely anonymized data and guarantee a highly secure content level. This protects individual devices from being associated with specific drivers.

Junction Analytics is powered by real-time traffic data from 600+ million GPS devices – giving you the definitive view of what’s happening at any intersection.

Monitor and improve the performance of your traffic light network with up-to-the-minute insights from TomTom. Junction Analytics combines real-time traffic data with intuitive analytics tools to help you understand how drivers move through intersections – so you can allocate green time in a better way to cut congestion, reduce pollution and boost road safety.
