Bluetooth traffic sensors installed on a four-lane highway in the Waikato region of New Zealand demonstrate significant journey time savings, according to a report by New Zealand engineering consultants Beca and the 6296 New Zealand Transport Agency (NZTA), Money well spent? The challenge of finding primary data.

To measure the effectiveness of the new expressway, Bluetooth sensors recorded traffic flows on the first stage of the Waikato Expressway for approximately three months before and after its opening. The sensors were configured to not only detect the journey time changes but also the relative proportion of traffic using the new and old routes.

The Bluetooth solution used by NZTA utilises BlipTrack sensors from Danish company 3778 Blip Systems installed in the road network. By anonymously tracking Bluetooth devices, such as mobile phones, tablets and hands-free installations in cars, it is possible to measure traffic flow and calculate journey time. This real time traffic flow data enables road authorities to proactively manage the road network to minimise delays and congestion.

BlipTrack sensors now cover over 600 km of state highway network on the North Island of New Zealand and are constantly being expanded.

    The 2010 Urban Mobility Report, published by the Texas Transportation Institute at Texas A&M University, concludes that after two years of slight declines in overall traffic congestion - attributable to the economic downturn and high fuel prices - leading indicators suggest that as the economy rebounds, traffic problems are doing the same. While 2008 was the best year for commuters in at least a decade, the problem again began to grow in 2009.

Technological advances and legislative changes pose many questions for those involved in road enforcement, ranging from the changing demands of privacy and data protection legislation to the practicalities on multi-speed enforcement. So to get the industry’s views ITS International took soundings on some of these bigger questions. In a world where many vehicles are fitted with GPS linked ‘black box’ telematics system

    September 15, 2014
    Caldecott Tunnel’s new Fourth Bore is utilising a bespoke high-capacity monitoring and communications network from Moxa. The Caldecott Tunnel connects Contra Costa and Alameda counties in Northern California and traditionally it has suffered severe congestion - especially during peak hours. Opened in 1937 as a twin-bore arrangement, by 1964 the increase in traffic volumes led to a third bore being added. Shortly after the third bore was opened a tidal flow was introduced with the centre bore alternating in
