This note presents the results of condition assessment of road marking performance in Region Norr (North), Sweden 2011. The measurements were carried out during the period 2-29 August by the use of the mobile reflectometer Ecodyn 30 to measure dry road marking retroreflectivity. Moreover, the reflectometer was supplemented with an optocator for estimation of wet road marking performance. From the results, the following conclusions can be drawn:

Dry road marking retroreflectivity:

- On European highways with ADT (Average Daily Traffic) more or equal to 4,000 vehicles per day, 43% of the measured objects fulfilled the requirements in the Swedish regulations.

- On other European highways and national roads, the corresponding figure was 69%.

- On county roads, 64% of the objects were approved.

- The performance of the road markings in Norrbotten county was better than in Västerbotten county on European highways with ADT more or equal to 4,000 vehicles per day. The difference between these counties was not statistically significant concerning the two other road types.

Wet road marking retroreflectivity:

- On European highways with ADT more or equal to 4,000 vehicles per day, 36% of the measured objects fulfilled the requirement in the Swedish regulations.

- The performance was better in Norrbotten county than in Västerbotten county.
