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.

    Perceptions of machine vision being an expensive solution are being challenged by developments in both core technologies and ancillaries. Here, Jason Barnes and David Crawford look at the latest developments in the sector. A notable aspect of machine vision is the flexibility it offers in terms of how and how much data is passed around a network. With smart cameras, processing capabilities at the front end mean that only that which is valid need be communicated back to a central processor of any descripti

    Bob Lees, co-founder of Diamond Consulting Services, on why the loop detector just refuses to go away. The more strident proponents of newer and emergent detection technologies are quick to highlight what they see as the disadvantages, and hence the imminent passing, of the humble inductive loop. The more prosaic will acknowledge that loops continue to have a part to play in traffic management, falling back on the assertion that it is all a question of application. And yet year after year the loop, despite

  • Improving urban traffic control in Atlanta
    January 27, 2012
    Hugh Colton, Georgia DOT details move to improve urban traffic control in the Atlanta area. With a significant proportion of traffic using freeways and toll-ways, along with a significant investment in roadway infrastructure, urban arterials are often the poor relation when it comes to ITS investment. Hitherto the primary means of Urban Traffic Control (UTC) has been the ubiquitous traffic signal. Many traffic signals still operate in a standalone mode and traffic detection is often broken, leaving the sign
