What is Mobile RWIS?

Mobile Road Weather Information Systems (RWIS) are advanced tools for road maintenance fleets that allow the recording and analysis of road conditions as part of an Intelligent Transportation System.

Utilizing sensors installed directly on fleet vehicles (such as snowplows), Mobile RWIS systems measure road conditions at incredibly fast intervals, providing a clear, accurate picture of road conditions not possible through stationary roadside RWIS stations.

Integration into Titan GPS offers road maintenance and Smart City operators a wealth of robust data for supporting decision-making, increasing efficiencies, and implementing cost-saving measures across an entire fleet.


  • Make intelligent decisions based on real-time data
  • Increase efficiencies with digitized mapping
  • Save money by eliminating manual reporting

Uses of Mobile RWIS Data

Winter roads are unpredictable – a dry road can turn to an icy stretch, back to dry, then to snow covered over a short distance. Static-positioned RWIS stations provide some insight into road conditions, but they only scratch the surface.

With Mobile RWIS systems equipped on fleet vehicles, making roads safer for travelers becomes a dynamic process. The data integrated into the Titan GPS dashboard allows fleet operators to ensure the most troublesome areas get the adequate attention needed, and safer stretches of road aren’t overdone, making for a more efficient operation.

  • Decision support for winter maintenance operators on roads, highways, municipalities.
  • Higher efficiency decision support for the de-icing of runways.
  • Essential competent of Ice Detection Systems (IDS) information of Runway Condition Codes (RCC), water film height (aqua-planning risk), and friction detection at airports.

Third Party Data Integration

Titan GPS supports the use of REST API for integration of Mobile RWIS data. When installed on any vehicle, data collected through a Mobile RWIS system can be externally shared with other third party solutions.

Vehicles equipped with either of the supported sensor systems can be used as patrol vehicles that collect the road data, which can be accessed and integrated with third party solutions either in real-time or historically. This method of data collection can stand alone or be used to supplement static RWIS systems, providing valuable insight that may be factor into a variety of process and decisions.

  • Labour and material cost planning.
  • Smart city applications.
  • Weather data collection and weather forecast model improvements.


Lufft MARWIS & Vaisala MD30

Titan GPS is compatible with two common Mobile RWIS systems, the Lufft MARWIS* and Vaisala MD30*.

By integrating these systems into Titan GPS, road maintenance fleets can access and analyze data that informs deployment and utilization decisions, ensuring fleet operators are providing the best service possible during the winter months:

  • Air Temp (°C)
  • Dew Temp (°C)
  • Humidity (%)
  • Water Depth (mm)
  • Ice Percentage
  • Road Friction
  • Road Temp (°C)
  • Surface Status:
  • Dry Moist, Wet, Ice, Snow & Ice, Chemically Wet, Water & Ice, Snow

*Mobile RWIS hardware is not available through Titan GPS. Data points may vary between hardware systems.
