Researchers at Waterford Institute of Technology (WIT) have developed sensors that can detect cyclists on roundabouts and alert drivers to their presence – with the project undergoing a trial in recent weeks – the Telecommunications, Software and Systems Group (TSSG) at WIT has confirmed, and which was first published in The Sunday Times.

The sensors use Bluetooth low-energy wireless transmissions, already used for short-range communications utilised by hands-free technology in cars.

“We use the technology to identify the position, direction and speed of cyclists on roundabouts, and relay this information to digital signs positioned on roundabouts,” said Steven Davy, researcher at TSSG. “[The system] allows motorists to be quickly informed about approaching cyclists and where they are on the roundabout.”

In trials of the technology, standard portable digital signs were used, with warning notices to motorists including messages such as “cyclists approaching from behind”, “cyclist approaching from right”, or “cyclists ahead”, said Davy.
