Innovations for more road safety and better traffic flow
VITRONIC is one of the leading vendors of systems that monitor free-flowing traffic. The initial spark was the development of the German truck toll system in 2003. This was the first time the LIDAR (Light Detection and Ranging) laser scanner measuring technology was used in a nationwide traffic project. VITRONIC has revolutionized traffic technology with this pioneering work. In 2005, the first POLISCAN SPEED type speed enforcement systems followed, which were enhanced in 2009 to enable monitoring of red light violations. Today, the distinctive pillars housing VITRONIC enforcement systems symbolize laser-based traffic monitoring "Made in Germany" in many cities around the world: The benefits of LIDAR technology are now available in more than 5,000 VITRONIC laser scanners around the world that help make road traffic safer and more efficient.
Better measurement through laser – LIDAR use in traffic technology
The LIDAR measuring technology is based on transmitting a "fan" of laser beams. VITRONIC systems use the duration and angle coordinates of the light pulses to calculate the location data for all vehicles within the laser fan. At a high repeat rate, this laser duration measurement allows the highly accurate calculation of a vehicle's travel path and speed. In addition, the vehicle class can be determined. The infrared-range measurements use protection class 1 lasers without any inconvenience to road users.
Laser measurement offers significant benefits compared to conventional technologies – both for traffic measuring technology and toll systems. LIDAR-based traffic technology made by VITRONIC is fully automated and able to clearly detect multiple vehicles and lanes simultaneously, even in heavy traffic and using a single system.
Laser measurement is virtually resistant to interfering reflections, which makes it ideally suited for use in traffic scenarios such as work zones or tunnels where radar systems often fail. Vehicles are tracked precisely until they reach the ideal photo point and then captured. This is also true for photo proof at red lights when crossing the stop line. This technology makes elaborate lane sensor embedding obsolete.
Fully automated LIDAR-based vehicle detection on toll roads enables enforcement in free-flowing traffic. No more irritating wait times at toll booths. This helps maintain traffic flow especially in urban areas and during peak times.
VITRONIC combines these benefits offered by LIDAR technology with its unmatched knowledge in machine vision systems to bring all the tools needed for automated traffic monitoring to customers all over the world.

POLISCAN SPEED sets a new standard for speed enforcement, it allows multi-lane and multi-target-capable speed enforcement with high capture rate and precise identification of violations even in difficult measurement settings.
No more stopping to pay a toll – VITRONIC's toll solutions for moving traffic mean that toll booths are a thing of the past. With this technology, also known as Multi-Lane Free-Flow (MLFF), the fee for using the road is calculated at normal driving speed, so no road users are inconvenienced.
Systems for automatic number plate recognition (ANPR) in free-flowing traffic enable individual vehicles to be identified quickly and reliably without intervening in the traffic flow and allow database matching for blacklist and whitelist applications.
