Q-Free has collaborated with Slovenian road operator Dars in the deployment of a new cooperative ITS (C-ITS) network in the eastern European country's capital, Ljubljana.

The system will enable equipped Volkswagen vehicles to receive in-car notifications such as traffic incidents, construction zones, low visibility alerts, and wrong-way driver warnings.

The new network sees 25 roadside units (RSUs) on more than 100km of Ljubljana’s major ring-road. These RSUs will transmit information to VW drivers, while receiving traffic flow information from them at the same time. 

Slovenia sits between Austria, Croatia, Hungary and Italy and is on a key freight route between the European nations. Q-Free says traffic volume, particularly around Ljubljana, has increased over the last few years, with some estimates suggesting a 5% annual rise. 

Q-Free and Dars have done something together on a smaller scale before: in 2018, a local pilot used nine RSUs with a central management system.

In this new deployment, Dars will also use five vehicle-mounted mobile units, probably around workzones and traffic incidents. 

“We put a high value on our relationship with Dars and though this solution is not part of our commercial portfolio, we decided to develop a customised solution that would exactly fit their needs,” explains Q-Free CEO Mark Talbot.

“I’m proud of our team for recognising that we’re not just in the traffic management business, we’re in the relationship business."

    Long-time industry leader John Worthington reflects on where transportation in the US is heading – and where it should be going. Interview with Jason Barnes. The US’s new transportation bill reflects much of what is wrong in the sector in general and in ITS in particular, according to John Worthington. While a decision is welcome, he says, it does little more than provide certainty of funding for anything other than day-to-day operations. Worthington, former Chairman and CEO of TransCore, is back in the ITS
