Danish city uses cell phone data to reduce travel times

The Danish city of Aarhus is using the anonymous data from drivers’ Bluetooth-enabled cell phones and GPS systems to assist them in reducing traffic congestion. Using Blip Systems’ technology and placing the small sensors in the road network, the road authorities can obtain traffic flow data in real time and proactively manage the road network to minimise delays and congestion.

The Danish city of Aarhus is using the anonymous data from drivers’ Bluetooth-enabled cell phones and GPS systems to assist them in reducing traffic congestion.  

Using 3778 Blip Systems’ technology and placing the small sensors in the road network, the road authorities can obtain traffic flow data in real time and proactively manage the road network to minimise delays and congestion.

The municipality started the project in 2011 and currently has nearly 40 sensors installed on the ring road, says project manager Michael Bloksgaard. He expects that when the BlipTrack solution is fully implemented by the end of the year, around 120 sensors will have been implemented.

According to Blip Systems, the solution has helped to optimise out-of-sync intersections and the roads administration has been able to record a reduction of 20 per cent in travel times on the ring road.

For decades, transportation planners and ITS visionaries all believed that transportation would not be fully optimised until it could be managed as a single intermodal system. Relationships between modal operators left this more in the dream category than reality. However, the steady march of advances in payment technology have brought us

    David Crawford reviews a new approach to traffic smoothing. A key objective for the Californian city of Bakersfield’s upgraded traffic operations centre (TOC), which opened in June 2014, is to help improve living conditions in a region with one of the worst air quality problems in the US. The TOC is speeding up the smoothing of traffic flows by delivering faster and better-informed traffic signal retiming and synchronisation.
