Danish company Blip Systems said it has signed a big data agreement with Trafik Stockholm, which is run by national highway authority Trafikverket and by the boroughs of Stockholm and Nacka. Trafik Stockholm will deploy BlipTrack to provide travel time and flow data to help alleviate congestion and supply road users with live information. Blip Track will be installed and organised by Danish company Dynniq.

The system works by placing BlipTrack sensors at strategic points along the roads. The sensors detect Bluetooth and Wi-Fi devices in mobile phones and onboard audio and communication systems. Specific and accurate statistical information, such as travel times, average speeds, dwell times and movement patterns, become available, said Preben Andersen, sales manager at Blip Systems.

Otto Astrand, Traffic Analyst at Trafik Stockholm, said it will use the collected data to display live travel times on information hub Trafiken.nu, and on Variable Message Signs (VMS) around the city.
