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.

The sensors have been installed at strategic locations around the city and following eight months of testing, the company says the non-intrusive system provides the same information as alternative and more expensive solutions such as ANPR and loops. Sixty sensors are currently installed around the city to monitor travel times, detect changes in traffic patterns and w

    The In-Time project is looking at the effect that multi-modal real-time traveller information services can have of reducing transport's energy consumption levels. By Martin Böhm, AustriaTech GmbH. Around the world, significant research and development effort is currently directed towards reducing energy consumption by addressing those areas where the biggest savings can be expected. European studies have shown that the transport sector has the potential to reduce its energy consumption by up to 26 per cent
