This note presents the results of condition assessment of road marking performance in Region Öst (East), Sweden 2011. The measurements were carried out during the period 16 June to 20 September 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, 48% of the measured objects fulfilled the requirements in the Swedish regulations.

- On other European highways and national roads the corresponding figure was 47%.

- On county roads 78% of the objects were approved.

- The performance of the road markings in Östergötland county was best and in Örebro county it was better than in Södermanland county. All other differences between the counties were not significant.

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 requirements in the Swedish regulations.

- The performance was worst in Södermanland county. All other differences between the counties were not significant.
