PTV Group and TomTom 

Paris’ main road and highway network is vast, made up of some 800 miles (1,300 km) of tarmac, where congestion and bottlenecks are a constant possibility. It’s up to Direction des Routes d'Île-de-France (DiRIF), the highway authority for the Paris metropolitan region, to manage this complex traffic situation.

To accomplish this task, DiRIF needs clear and accurate insights into the state of traffic on the roads. For years, the agency has relied on its own detectors to monitor traffic flows. Since July 2023, the agency has added a new tool to track and tackle congestion — real-time traffic management technology from PTV Group, powered by TomTom Traffic data.

Using data from DiRIF’s own road-side sensors and TomTom Floating Car Data, PTV’s algorithms generate highly accurate, real-time information about Paris’ traffic. TomTom’s Floating Car Data gives PTV Group and its customers access to rich and fresh information about what’s happening on the roads. Part of a 600-million-strong community of devices and sources, Floating Car Data is an irreplicable asset in any traffic manager’s toolbox.

DiRIF has also integrated this data into its traffic platform Sytadin.fr. This online service provides real-time traffic information to users on the main road network in Île-de-France and is accessed by around 100,000 people every day.
