The Belgian state expects the tolling of trucks weighing less or equal to 3.5 t to provide annual revenue of US$976–US$1.1 million. The sky-ways consortium, comprising Strabag and satellite tolling provider
Efkon will deliver the enforcement technology, including software for the enforcement control centre, the technology for 40 stationary enforcement sites, the equipment for 40 mobile enforcement vehicles and the delivery of 22 portable enforcement units.
Installation of the system, its trial operation and the full and complete implementation are scheduled for an 18-month period beginning in July 2014. Tolling will start in 2016. Operation and maintenance by Strabag has been agreed up to 31 December 2027.
