This note presents the results of condition assessment of road marking performance in Region Mitt (Middle), Sweden 2011. The measurements were carried out during the period 18 June to 15 October 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, 40% of the measured objects fulfilled the requirements in the Swedish regulations.

- On other European highways and national roads the corresponding figure was 23%.

- On county roads 28% of the objects were approved.

- The performance of the road markings was best in Jämtland county. Gävleborg county had a higher percentage of approved road markings than Dalarna county, whose performance was similar to Västernorrland county.

Wet road marking retroreflectivity:

- On European highways with ADT more or equal to 4,000 vehicles per day, 25% of the measured objects fulfilled the requirements in the Swedish regulations.

- The performance was equal in the two counties where wet road marking function was estimated.
