The Municipality of Koege, near Copenhagen in Denmark, is set to use Blip Systems’ Bluetooth service, BlipTrack, in a bid to ease traffic jams.

Koege has allocated funds of around €1.3m to improve junctions with high traffic jams and sees BlipTrack as the ideal solution.

Koege Municipality civil engineer Thomas Meier said: "BlipTrack makes it possible to see how poorly a traffic signal handles the traffic and to address the problems."

Initially developed to measure passenger flow at airports, BlipTrack is currently used in various international airports.

The BlipTrack system features two boxes attached to posts on a traffic-congested road that detect Bluetooth signals from cars and record the time it takes for a car to travel between the boxes.

"Koege has allocated funds of around €1.3m to improve junctions with high traffic jams and sees BlipTrack as the ideal solution."

Around 27% of all drivers have a Bluetooth device, such as a mobile phone, which the BlipTrack system can capture data from.

This data is encrypted, making it impossible to relate the Bluetooth address of a device to an individual, and help the area to accurately understand the traffic situation.

Koege had previously hired local students to write down the number plates of passing cars to get a picture of the congested roads.

BlipTrack uses Bluetooth and Wi-Fi signals to track the flow of movement in airports, road traffic and transportation hubs.

The system is currently installed in several airports, including Schiphol Amsterdam, Toronto Pearson and Dubai International.
