Accurate roadside visibility monitoring

The SWS-050 visibility sensor for roadside monitoring developed by UK company Biral measures local weather conditions and instantly relays this information to road users via electronic signage, warning drivers of unexpected hazards such as fog patches and enabling rapid response by authorities in the event of dangerous conditions. With a measurement range of 10 metres to 40 kilometres, the SWS-050 operates in temperatures ranging from -40ºC to 60ºC and is unaffected by local lights or reflections. The devic

Biral SWS-050 roadside visibility sensor
The SWS-050 visibility sensor for roadside monitoring developed by UK company 7359 Biral measures local weather conditions and instantly relays this information to road users via electronic signage, warning drivers of unexpected hazards such as fog patches and enabling rapid response by authorities in the event of dangerous conditions.

With a measurement range of 10 metres to 40 kilometres, the SWS-050 operates in temperatures ranging from -40ºC to 60ºC and is unaffected by local lights or reflections. The device is provided with heated hoods and window heaters, allowing continued operation in blizzard conditions and preventing condensation forming on the optical surfaces. 

The sensor is a single lightweight unit constructed of high-grade aluminium, robust enough to easily withstand aggressive roadside conditions for many years with minimal maintenance. Typically installed within three metres of the roadside, the SWS-050 provides digital data that integrates easily into any control system, allowing authorities to make timely traffic and road management decisions.  The forward scatter design technology, infra-red light source and intelligent sensing technology gives the SWS-050 proven accuracy, reliability and repeatability.

  • Wireless traffic data in real time
    January 31, 2012
    The effect of moving objects on the electromagnetic landscape set up by cellular telephony networks can be detected and interpreted to give real-time traffic data across large geographical areas at low cost. Here, we revisit the Celldar concept. Global economic downturn has pushed public-sector agencies, transport administrations among them, to push even harder for cost efficiencies. Unfortunately, when it comes to transport safety and efficiency the public sector often has to work up to a cost rather than

    June 11, 2015
    The adaptation of machine vision to transport applications continues apace. That the machine vision industry is taking traffic installations seriously is evident by the amount of hardware and software products tailor-made for ITS applications that are now available on the market. A good example comes from US-based Gridsmart Technologies which has developed a single wire fisheye camera that provides a horizon to horizon view for use at intersections. Not only does the single camera replace four or more in a

  • Telensa lights up Hertfordshire
    November 27, 2014
    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
