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.

    Pete Goldin reports on a new wireless, solar-powered traffic detection system being used by Caltrans District 12. As more and more traffic data is necessary to satisfy the needs of traffic management centres and traveller information systems, and as traffic detection technology becomes more ubiquitous, transportation authorities are pressured to find more economical ways of expanding their detection systems. Caltrans District 12 is leading this push by deploying the latest detection system from Case Global

    As part of a wider Hertfordshire County Council strategy to ease congestion across the county, the council is installing variable message signs to provide live incident information, managed by a centralised control centre at County Hall. The centre opened in October last year at a cost of around US$600,000 and is operated by eighteen staff, who monitor the county’s road network. If an accident occurs, traffic signals can be adjusted and messages displayed in a bid to redirect traffic ease congestion. Mainte
  • Study finds big differences in toll collection cases

    Examination of Norway’s tolling companies finds much to praise, and some criticisms too, as Torill Eidsheim told delegates at the ASECAP conference. The cost of collecting tolls has a substantial effect on the profitability, or otherwise, of tolling companies and is within the company’s control to a far greater degree than, for instance, traffic volumes. And while it is easy to assume that all tolling companies incur similar collection costs, that is not always the case according to Torill Eidsheim, pres
