French government orders 100 additional Vitronic speed enforcement trailers

The French Ministry of the Interior has placed an order for an additional 100 autonomous mobile Enforcement Trailers, in order to extend the country’s nationwide speed enforcement program, particularly in locations where continuous speed enforcement is not an option. These areas include rural roads and work zones, which do not have the necessary power and data connections to allow the deployment of permanent camera systems.

The new order follows up on an initial procurement of 150 Enforcement Trailers from the German company Vitronic, which was placed in April 2015. The systems have proven to be extremely effective, with single units documenting up to 2,500 speed violations per day in certain locations. The Ministry has found that the systems are particularly beneficial in areas where traditional mobile measuring systems are not a suitable alternative, as they do not have a sufficiently long life, and cannot be used unprotected for long periods. The autonomous mobile lidar systems can operate on their own for a minimum of five days, and will mainly be deployed on the French National Road network.

The Enforcement Trailer is a system for traffic monitoring that makes zero demands on the local infrastructure. The system is a joint development between Vitronic and its partner in the project, the French electrical engineering company CEGELEC Equipments Dynamiques Routiers. The Enforcement Trailer has an independent power supply based on high-performance batteries, enabling uninterrupted operation for five days.

The measurements are performed by Vitronic's PoliScanspeed lidar measuring technology, which allows authorities to enforce speed limits of all vehicles across all lanes simultaneously. The system can also monitor variable speed limits and bans on through traffic, specific to certain times, lanes and vehicle classes. An integrated modem transfers case data wirelessly via GSM, and enables remote access to the measuring system.

The system can therefore operate autonomously, without any human intervention, leading to a significant increase in efficiency. It is also ideally suited for use in hazardous areas, where speed enforcement with mobile speed enforcement systems cannot be used because of the risk to the operator. The Enforcement Trailer can be transported by virtually any vehicle that has a tow bar, and the trailer also has its own remote-controlled engine for easy and precise alignment on site. Once in place, the trailer can be lowered down to ground level, making it much more difficult for it to be moved by unauthorized parties. The system also has an armored outer shell, and an alarm system that protects the technology against vandalism.

The contract will run over two years, and comprises delivery, operation and on-site and remote service. The French government hopes that the system will help reduce the approximately 200 traffic accidents that occur in the vicinity of work zones on its roads annually, which result in multiple fatalities and around 80 injuries.
