Sernis lights the way with road studs for harsh conditions

Portuguese manufacturer Sernis has introduced the SR-40, a reflective road stud that is very much at home in harsh conditions and is snowplough-resistant. Its design includes a solar panel of less than 1W in power, making it perfect for countries with low sun exposure. The stud also has RF low power 868MHz mesh network communication and has microcontroller technology inside each stud. Features include a wake up and sleep function, automatic brightness control and night-level contraction.

Portuguese manufacturer 7640 Sernis has introduced the SR-40, a reflective road stud that is very much at home in harsh conditions and is snowplough-resistant. Its design includes a solar panel of less than 1W in power, making it perfect for countries with low sun exposure.

The stud also has RF low power 868MHz mesh network communication and has microcontroller technology inside each stud. Features include a wake up and sleep function, automatic brightness control and night-level contraction.

The stainless steel, aluminium and polycarbonate body house two uni-directional LEDs and four bi-directional LEDS.

To complement the SR-40, Sernis has produced another snow-plough resistant stud, the inductive power SR-45 IPW. Installation is easier through the plug-and-light concept. A non-wired connection prevents unnecessary drill and deterioration of the road in future interventions. And all road studs are connected to the Control Central Unit to allow several control features.

The 3kg SR-45 IPW uses 230 volts AC and its 8 LEDs consume 5 Watts of power. Sernis says it is suitable for use in roads, tunnels, parks and airports.

    Wireless transmission of data and control information is making smarter traffic management easier and cheaper to install. It has long been known that connectivity is the key to improving traffic management and many cost-benefit studies prove that investment in new technology can be justified in terms of reduced congestion, shorter travel times, improved safety and air quality. However, many authorities’ cap-ex budgets only cover urgent matters, not improvements, making it difficult, if not impossible to

    The new Hindhead Tunnel is the first in the UK to use radar-based incident detection. Paul Arnold, project manager with the Highways Agency, talks about the project. The comparatively remote location of the A3 Hindhead Tunnel has resulted in it becoming one of the most sophisticated in the UK in terms of monitoring and control systems, according to Paul Arnold, project manager for the Highways Agency (HA), which manages strategic roads in England and Wales. It is the first tunnel in the UK to use radar for

    More than 12,600 street lights on Hertfordshire’s A-roads are being upgraded to LED lighting using Telensa’s PLANet street light central management system (CMS), which will allow the lights to be monitored from a central point. This will reduce inspection costs and make it easier to spot and repair any faults. The system will also allow lighting levels on the A-roads to be reduced during the night, rather than turning lights off completely. Once the new lights are installed, light levels will be reduced
