CGS Road WeatherInformation SystemOptimization of road winter maintenance
Weather affects all modes of transportation.
Road Weather Information System (RWIS)
technology provides vital information on pavement
and weather conditions needed for roadway
maintenance operations.
RWIS technology is typically used for monitoring
snow and ice, but it can also be used for high
winds, flooding, or visibility.
RWIS enables maintenance and operations
personnel to monitor changing weather conditions
in real time and make informed and timely
decisions.
That
is why

RWIS and road weather forecast
The RWIS can be equipped with a reliable energy-balance
model for forecasting the temperature and road surface
conditions (e.g. dry, moist, wet, frost, ice, snow) with high
time and spatial resolution (1km). The users have access to a
12-hour point forecast, which is updated every hour.
Nowcasting products of meteo services are integrated.
Description of CGS RWIS
Road weather stations (RWS)
RWSs are equipped with embedded or contactless road sensors, meteorological sensors, and with digital cameras. Most common
measurements on RWS are: road temperature (on surface and in different depth), thickness of water film, salt concentration,
freezing point temperature, road condition, air temperature and humidity, dew point, air pressure, amount and type of precipitation,
visibility, wind speed and direction. The measurements are stored in the station's logger.
Road weather information system (RWIS)
From the RWS logger, the measurements are transferred by
different telecommunications technologies to the central
database of the road weather information system (RWIS),
which is a web-based application offering various displays of
current measurements at RWS locations, displays of the
archived data and the metadata on stations and sensors. The
application can also trigger alarms. 'Opened' system supports
RWSs of different producers and is custom-designed.

In the future, our system will offer also a forecast for road
sections and modules for management of resources (means of
transport, spreading materials, available human resources) and
it will thus become an integrated maintenance decision
support system (MDSS).
CGS RWIS is 'opened' system which supports RWSs of different
producers. It's custom-tailored solution. High tech and high
resolution (time and spatial) road weather forecast supports
maintenance operations. CGS RWIS is compatible with
nowcasting products of meteo services.
