Observator offers a wide range of sensors and weather stations to monitor the condition of the road in real-time. Intelligent active and passive sensors for flush-mounting into the road or runway surface. Nowadays more and more interest is shown for non-invasive measurements using the optical principle. In addition to road condition sensors, Observator has also many sensors and systems, that are used on bridges, within tunnels, nearby highways, to measure local meteorological and other parameters. Important decisions either automatically or through human intervention, are taken on this vital information.

The following variables can be measured with the serveral sensors:

• road surface temperature
• water film height
• freezing temperature
• road condition (dry/damp/wet/ice/slush/snow/residential salt/freezing/friction (grip)/ice percentage)
• visibility
• present weather
• precipitation
• snow depth
• air temperature
• relative humidity
• barometric pressure
• solar radiation
• wind speed- and direction

Observator’s software program OMC-Data-OnLine, is capable to collect, view and manage data from all sensors in real-time, fixed as well as mobile ones, into a single database.
