The city of Aarhus in Denmark is utilising BLIP Systems’ technology (a mix of Wi-Fi and Bluetooth) as an important weapon in the fight against traffic jams.

By placing the small sensors in the road network, the road authorities have been able to obtain traffic flow data in real time and proactively manage the road network to minimise delays and congestion. The project began in 2011 and to date 40 sensors have been installed along the ring road. Once the BlipTrack solution is fully implemented, around 120 sensors will be in operation.

The Road Administration has reported that travel times on the ring road have been reduced by up to 20 per cent. This not only leads to significant economic benefits for the municipality through reduced travel times and fuel consumption, but it also reduces CO₂ emissions and improves air quality.
