At the end of August, the workforce at AVS Overath GmbH said goodbye to their longstanding colleague Norbert Eikel as he went into his well-deserved retirement. Dipl.-Ing. Norbert Eikel worked for AVS for many years, initially as site supervisor. Subsequently he was responsible for calculating the company's professional traffic-safety services. He was very popular with his colleagues for his calm manner and his comprehensive know-how. He always gave special priority to ensuring that AVS installation fitters and site supervisors receive outstanding initial and advanced training for their highly responsible tasks. On his last day at work, Norbert Eikel said goodbye to his colleagues over a cup of coffee and a piece of cake. They have become friends over the years and he left them with a twinkle in his eye as he quoted Heinrich Zille: "How marvellous it is to do nothing, and then relax from doing nothing." With these words, the whole AVS team in turn wishes him all the very best for this new chapter in his life, and lots of time for "doing nothing"! Particularly at one-day roadworks on multilane roads and motorways, safe traffic control depends on informing road users clearly about the changed road layout and approaching roadworks. Unfortunately, temporary signs and even LED prewarners placed at the side of the road are often overlooked, because they are concealed when large vehicles drive past. The mobile overhead signs with our Berghaus TOP LED are bright and clear with LED technology at a height of six metres above the carriageway, actively drawing attention to the approaching hazard. They also warn road users on the fast and middle lane, whose view of the conventional roadside prewarner is concealed by passing traffic. The overhead warning can be seen from a great distance, clearly visible above the roofs of trucks and high-sided vehicles, this having a positive impact on the safety of all road users as well as the workers at the upcoming construction site. In addition to the LED side prewarner, the large overhead LED sign fitted in landscape format over the road can also be used to display a wide range of road signs, texts, information and moving images. Operation is similar to our LED prewarner, with a large library available directly at the unit or per radio remote control, which can be supplemented easily with individual texts, symbols and moving images. The Berghaus TOP LED can be used across the full width of its continuous overhead LED sign, so that simultaneous or different signs can be shown for more than just two lanes. continues on page 3 Mobile width measuring system for heavy loads Photo showing installation of the mobile width measuring system on the A2. Wide-load vehicles driving into the roadworks are reliably registered by the overhead detectors. Automatic LED traffic lights then temporarily block the feeder roads for the Langenhagen and Bothfeld junctions. The tender specifications issued by the Lower Saxony State Authority for Road Construction and Transport for the work involved in resurfacing the A2 motorway around Hanover included among others the installation of a width measuring system. In cooperation with our partner company MIS GmbH Mobile Information Systems, we installed two temporary arm masts with overhead detectors and corresponding control in the approach to the Langenhagen and Bothfeld junctions on the Berlin-bound carriageway. LED information signs with mobile concrete foundations were also set up at both motorway junctions for temporary on-request traffic control. The detectors register a wide-load vehicle as it drives through the measurement cross-section. The LED information signs at the above-mentioned motorway junctions are then automatically activated for a defined period of time and block the two feeder roads leading onto the motorway. As a result, the wide-load vehicle can pass safely through the narrow roadworks without being influenced by other merging traffic driving onto the motorway.
