In 2016, the Hungarian government implemented an automated, legally binding measuring system to detect overloaded vehicles and directly enforce weight limits on roads all over the country. Kistler supplied 1518 Lineas WIM Sensors to measure loads on vehicles moving at high speeds (Weigh In Motion). Delivery, installation and calibration were completed within just one year.
The worldwide increase in road usage is confronting governments, road owners and operators with the challenges of monitoring traffic and maintaining highways. These tasks are difficult, labor-intensive and critical – because frequent overloading of trucks can quickly damage roads. In response, growing numbers of authorities and operators across the globe are switching to automated solutions. Automated technology yields many benefits: for instance it frees up local police forces to focus on important security tasks.
Weigh In Motion (WIM) technology is the solution of choice for traffic monitoring, weight enforcement and weight-based tolling. A well-established WIM system is the key to sustainably managing and protecting the road infrastructure. This was why, in 2014, the Hungarian Ministry of National Development decided to implement a nationwide Weigh In Motion system based on existing toll collection sites. The two-year preparatory phase included setting up the legal framework, issuing the tender for the technology providers and developing the entire software and back-office concept. Implementation began in 2016 with a pilot project across five sites.
The Weigh In Motion system became fully operational in 2018, with 89 sites throughout Hungary – by far the largest European project of its kind in recent times. As well as Kistler's WIM sensors, the system comprises loop detectors, license plate recognition, laser scanners for vehicle categorization, signal processing end point devices, and the related central information system. To make the changeover easier for road users, direct weight enforcement was preceded by a transition phase when violators were only given an official warning but were not penalized.
