This note presents the results of condition assessment of road marking performance in Region Syd (South), Sweden 2011. The measurements were carried out during the period 20 May to 21September 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, 74%

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

- On other European roads and national roads the corresponding figure was 61%.

- On county roads 67% of the objects were approved.

- The performance of the road markings in Kalmar county was worst. In the other counties, a similar percentage of the road markings were approved, however, was Skåne county significantly better than Jönköping county.

Wet road marking retroreflectivity:

- On European roads with ADT more or equal to 4,000 vehicles per day, 65% of

the measured objects fulfilled the requirements in the Swedish regulations.

- The performance was best in Blekinge county. For three of the other counties, Jönköping, Kronoberg and Skåne, no significant differences were found. Road markings in Kalmar county had the worst condition (however, the difference was not significant between the counties of Kalmar and Kronoberg).
