This note presents the results of condition assessment of road marking performance in Region Väst (West), Sweden 2011. The measurements were carried out during the period 2-6 June 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, 59%

of the measured objects fulfilled the requirements in the Swedish regulations.

- On other European highways and national roads the corresponding figure was 50%.

- On county roads 71% of the objects were approved.

- The performance of the road markings in Halland county was better than in Västra Götaland county. The difference between Halland county and Värmland county as well as Värmland county and Västra Götaland county was not statistically significant.

Wet road marking retroreflectivity:

- On European highways with ADT more or equal to 4,000 vehicles per day, 54%

of the measured objects fulfilled the requirements in the Swedish regulations.

- The performance was better in Halland county and Värmland county than in Västra Götaland county. The difference between Halland county and Värmland county was not statistically significant.
