The article presents the results of road tests related to repeatability evaluation of the mobile road weather sensor readings. This kind of sensors is increasingly used by road administrators to assess current state of roads. They can be also used to identify road sections where local changes in friction occur most often. The carried out tests concern the repeatability of readings for different lighting conditions (day and night) and vehicle speed. The research was performed using the Lufft MARWIS sensor on roads with different traffic intensity and different standards of winter maintenance.
