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.

    Returning travel times to normal within two hours of the end of a major football game was the challenge facing College Station, Adam Lyons explains how this was achieved. College Station, TX, also known as ‘Aggieland’, is located right in the middle of the Dallas/Fort Worth, San Antonio and Houston triangle making the city accessible to over 14 million Texans within less than a four-hour drive. One of the biggest draws to this area is Texas A&M University (TAMU) and the Aggie football games in the fall, mea

    Managed lanes have something of a patchy track record and can pose authorities problems as well as solutions. Many authorities in the US and beyond have converted, or are converting, parts of the highway network into ‘Managed Lanes’ and charging motorists a fee to avoid the delays on the adjoining free use lanes. Some authorities have converted underused High Occupancy Vehicle (HOV) lanes into priced-managed high occupancy/toll lanes (HOT lanes) whereby the price charged can vary depending on a number of fa

    As part of a growing effort to use technology to manage traffic on roads and highways without building more roads, for the last six months Florida’s Palm Beach County has been using Bluetooth readers to determine how long it takes motorists to travel along its corridors. "We're adding more capacity through technology rather than asphalt," said Dan Weisberg, Palm Beach County's traffic engineer. "We can't build ourselves out of congestion. We need to be smarter about what we have and manage it." In collabor

    With five years of traffic disruption ahead and an inadequate traffic monitoring system, the authorities in Riyadh needed a solution – and quickly. In preparation for embarking on what is currently the world’s largest metro construction project, the Arriyadh Development Authority (ADA) in Riyadh needed to put in place measures to minimise the additional congestion and travel delays the five-year project would inevitably cause.
