Title:
Measurement of Road Climatological Variables
Abstract:
In order to perform temperature measurements of high quality it is essential to have good control over factors that influence the measurements. Location of field stations and sensors are example of such factors that will influence the accuracy and how well the performed measurements can give valuable information to maintenance personnel. In this project 11 stations were studied in relation to the above-mentioned factors. The results show that the stations differs a great deal both with respect to location of the station in relation to the road surface and the location of the stations. Especially regarding the road surface temperature sensor, it is important to have proper knowledge about the depth and pavement. Control measurements with use of IR-technique showed that large temperature differences can occur between sensor and surface.
