Road weather information system

Depending on the requirements, Observator Instruments can deliver a single sensor, but also an in-house developed, complete and fully integrated road weather information system.

The exact location can be determined by so-called thermal mapping, which can be done with the Marwis.

The following variables can be measured:

  • Road surface temperature
  • Water film height
  • Freezing temperature
  • Road condition (dry/damp/wet/ice/slush/snow/residual salt/freezing/friction (grip)/ice percentage)
  • Visibility
  • Present weather
  • Precipitation
  • Snow depth
  • Air temperature
  • Relative humidity
  • Barometric pressure
  • Solar radiation
  • Wind speed and direction
