Road surface condition sensor
Sensor is used to control:
- water layer thickness
- water layer thickness
- snow layer thickness
- ice layer thickness
Measurements are taken continuously (24 hours a day), collected data is transmitted at certain intervals or by request.
Sensor is a compact module that is attached to the pillar at the height of 5 to 10 meters.
The data received is used to manage snow removal, anti-icing coating application and to determine whether cleaning is necessary. Warnings over road conditions can be displayed to drivers on special information panels. Using the data improves road safety and road maintenance quality, reduces maintenance costs and the number of complaints and fines.
Software
The road condition monitoring system is a part of Unilight platform. One interface makes it possible to
use AOLCC, automated power metering system etc.
Archive data can be presented as a table or a graph. Reports can be downloaded in Excel, PDF and other formats.
