- 6. Eutectical point Each measurement of the freeze point temperature depends on salt concentration AND existing water film. The more water on the surface the higher the salt concentration to bring down the freeze point. Vice versa, in case of declining roads, there is a high risk of oversalting the road. In this case, the EUTECTICAL POINT is exceeded, the corresponding result is ice formation. UMB sensors

Editor's Notes
- First of all, reliable and precise data directly from the road pavement are an essential requirement for maintenance decision support and road weather information. In order to make it affordable to densify the acquisition network on the road, easy to install, compact, intelligent and maintenance friendly devices are necessary. The German company LUFFT has developed intelligent devices both for road pavement condition detection and for atmospheric road side weather situation. A complete road weather remote station can now be composed of two sensor devices only – the minimum amount possible. Road Weather and environmental remote stations should be well arranged and arbitrarily extendable. The, so called, UMB Technology provides – among others - these sophisticated features. The Technology also is designed for low power consumption – which allows – under certain conditions - solar or/and fuel cell power supply assembly. Each top hat rail plugged UMB Module can control one Sensor or a complex sensor device. A mobile Phone network communication can be established by adding a GPRS Module. National or international line communication protocols, such as TLS or NTCIP can be supported by adding a so called “LCOM” Module (based on a small top hat rail mounted Industrial PC).

- In order to provide local acting organizations a smart and easy to install standard central computer solution on a PC, SMARTView software system was developed. The SmartCom collector software controls the data acquisition from remote stations. Supporting different communication media makes it easy to choose the optimal and cost effective way for the application. The data were directly stored in a SQL standard database. Around the database application specific modules can be installed. For winter maintenance users it is important to view the information with standard tools from different places within a computer network. SMARTVIEW therefore has also a WEB Interface. The display adapts itself to the setup of the remote station. Visual inspection of the road condition is the most informative way. Together with accurate measured data, experienced people can gain a full knowledge about the actual situation on site. Still pictures can be taken in certain intervals and together with the measured data transferred to the central computer or to the service platform.
