Successful partnership: RR Kommunal and Adolf Thies GmbH & Co. KGFor more than a decade,
RR Kommunal has been working successfully with Adolf Thies GmbH & Co. KG. The partnership began on September 26, 2011 with the first delivery of the innovative
Laser Precipitation Monitor (LNM / LPM) . Since then, more than 300 of these high-precision devices have been installed to increase road safety on Austriaʻs roads.
Background: The aim of
ASFINAG , the operator of Austriaʻs highways and expressways, was to introduce an open weather information system (
OpenWIS) to improve traffic monitoring and safety, into which sensors from various manufacturers can be integrated. RR Kommunal was able to impress with the design of an innovative measuring station that included the Thies CLIMA LPM alongside other sensors.
The Thies CLIMA LPM: robust and precise. The Thies LNM has established itself as an excellent measuring device for recording precipitation intensity and type. The device is characterized by high accuracy and reliability, which is why it is predestined for traffic applications. "The Thies LNM meets the requirements of
CEN/TS 15518-4 and is therefore recommended for use in winter road maintenance," explains Marc Hillebrecht, Export Manager at Thies CLIMA. High sensitivity and flexibility: The special ability of the Thies CLIMA LNM is to detect all types of precipitation, including drizzle, very precisely. The LNM also impresses with its high sensitivity. "We are always surprised at how sensitively the Thies CLIMA LNM reacts, especially in drizzle," adds Markus Riedel.
Extract from the technical specification:
- Particle size: 0.16 ... 8 mm
- Particle velocity: 0.2 ... 20 m/s
- Intensity: < 0.001... 1000 mm/h
Overview of accuracy: comparison with synoptic observation:
- Drizzle > 97%
- Rain > 99%
- Hail > 97%* According to human observer
- Snow > 99%
- Sleet > 85%
- Snow drizzle > 60%
Integration into modern traffic infrastructure:ASFINAG is continuously investing in the modernization of the Austrian freeway network with the aim of implementing modern safety technologies and meeting the latest EU standards.
The experience of our partner RR Kommunal is also reflected in the evaluation results of the
Federal Highway Research Institute (BAST Bundesanstalt für Straßenwesen) . The Thies Laser Precipitation Monitor (LNM) was installed in December 2015 and achieved top marks in the
following categories in a multi-year comparative study that ran until 2019:
- highest agreement with synoptic observations.
- the LNM was the only sensor to deliver measured values, particularly for very short precipitation events such as snowfall or hail
- Low-maintenance operation
These evaluation results from the BAST (Federal Highway Research Institute) serve as a reference and underline the accuracy and reliability of the Thies LNM.
We look forward to continuing to develop innovative solutions together with RR Kommunal in the future and to further strengthening our partnership.
