Road weather stations (RWS)

Road traffic is affected not only by the quality of pavement and traffic density, but also by weather conditions. Not always forecasts coincide with the actual state of the rivers. Sometimes drivers encounter unexpected road icing or find themselves on red-hot asphalt where their tires melt. To avoid negative consequences of the weather we offer installation of road weather stations.

Our company is engaged in installation of RWS for operative control of the situation on the road. A reliable system of sensors allows:

  • monitor any fluctuations in the weather;
  • Transmit data promptly to special services, servicing the roads;
  • to warn in advance of dangerous situations;
  • to control the road warning signs;
  • improve the traffic information system.

Features of a road weather station

When installing AMF, the customer chooses the necessary monitoring sensors himself. In addition to equipment the system includes the top-level module “Environmental Monitoring”, working on the Invipo platform. The software allows you to quickly track and notify the state of the road surface, temperature, humidity, wind speed, presence and intensity of precipitation. With AMF, winter road maintenance becomes simple and effective.


Advantages of road weather stations

AMF allows you to monitor even the smallest changes in the environment in real time. The software illustrates climatic fluctuations by means of graphs. All data is stored in Invipo, where you can view the history over a long period of time.

Any changes are recorded and forwarded to external messaging sources. Sending to email is also possible. If traffic information monitors are available, weather data is displayed to alert drivers at the right time.

The system is autonomous and doesn’t need any staff presence. All measurements are made automatically without stopping the traffic flow. AMF system equipment is installed on the artificial constructions and in the road clothes according to the requirements to the device and technical equipment of AMF systems.

The system is used in uninterrupted mode of operation 24 hours a day, 7 days a week.


The functionality of the AMF system can include the following:

wind speed and direction (ultrasonic sensor)
air temperature and humidity atmospheric pressure
dew point
intensity and type of precipitation (rain/snow)
horizontal visibility roadway conditions (dry, wet, wet, ice, snow, critical moisture, liquid reagents)
road surface temperature
water/ice film height
percentage of ice in the water film
coefficient of surface training/cohesion (calculated automatically by the internal processor based on the measured parameters).

Due to the fact that the weather station has a modular architecture, it can be built according to the technical conditions of the installation and the required composition of the measured parameters.

The composition of the complex can be changed at the customer’s request.

The road weather station allows you to monitor weather data online. The leather weather station saves measurements even in the absence of the network.

The meteorological information system includes a system for monitoring and forecasting of weather conditions on roads to manage maintenance and support winter road maintenance.

The software is designed to:

– management of measurements of meteorological quantities,

– automatic collection and presentation of measurements results,

– formation and archiving of meteorological information,

– diagnostics of measuring instruments

The software provides the survey of the automatic weather station, weather sensors and data transfer to the decision-making center via optical lines and GSM communication means, reception of the digital information coming from the data of the weather stations and sensors, recalculation and transformation into the digital values and graphs, as well as display and presentation of the information to the workplace and road signage.

The weather station data is the source of data for the ITS. Leather weather station has the ability to provide data to the integration system INV.

IPO, a platform for managing systems within the ITS. Through this integration:

– The operator has the ability to analyze weather conditions,

– The data from the weather station is displayed on the VMS,

– ITS stores historical data that can be analyzed, the weather stations are part of the ITS ecosystem
