Swedish transport administration Trafikverket has signed a design and build contract with Q-Free to upgrade Stockholm’s road congestion charge system.

The 130m NOK ($15.1m) deal is to revamp the technology including a new camera platform and updated automated number plate recognition software solutions. The Swedish capital’s road charging system was originally delivered by Q-Free in 2005.

The company says: “For 15 years it has contributed to reduced congestion, improved air quality and a modernisation of road infrastructure.” The new contract includes 10 years of service and maintenance.

“We are extremely proud and pleased to continue as the supplier of Stockholm’s congestion tax system,” says Håkon Volldal, Q-Free president & CEO.

“Stockholm has for many years been a showcase for Q-Free’s video tolling technology and will continue to be a very valuable and relevant reference as a growing number of cities around the world follow in Stockholm’s footsteps and implement city tolling or congestion charging schemes.”
