This note presents the results of condition assessment of road marking performance in Region Stockholm, Sweden 2011. The measurements were carried out during the period 28 June-7 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, 38% of the measured objects fulfilled the requirements in the Swedish regulations (Stockholm county).

- On other European highways and national roads the corresponding figure was 13% (Stockholm county).

- On county roads 19% of the objects were approved.

- The performance of the road markings on primary roads was better on Gotland than in Stockholm county. However, when taking all road types into account, there were no significant differences between the counties in the region.

Wet road marking retroreflectivity:

- On European highways with ADT more or equal to 4,000 vehicles per day, 29% of the measured objects (Stockholm county) fulfilled the requirements in the Swedish regulations.
