VTI has performed measurements for condition assessment of road marking performance in Sweden 2011. The measurements were carried out using the mobile reflectometer Ecodyn 30 to measure dry road marking retroreflectivity. The measurements were supplemented with an estimation of wet road marking performance. From the results, the following conclusions were drawn:

Dry road marking retroreflectivity

- On European highways with ADT (Average Daily Traffic) more or equal to 4,000 vehicles per day, 53 per cent of the measured objects fulfilled the requirements in the Swedish regulations.

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

- On county roads 49 per cent of the objects were approved.

- The performance of the road markings was best in regions Norr, Öst och Syd, with Syd as the best one (significantly better than Öst, however, the Syd result was not significantly different in comparison with Norr). In region Väst about half of the road markings were approved while the worst performance was found in the regions Mitt and Stockholm.

Wet road marking retroreflectivity

- On European roads with ADT more or equal to 4,000 vehicles per day, 44 per cent of the measured objects fulfilled the requirements in the Swedish regulations.

- The performance was best in regions Väst and Syd (there were no significant differences between them). In the other regions (Norr, Mitt, Stockholm and Öst) the performance was worse.

The reports for each region are the following:

VTI notat 8:1-2012 – Condition assessment of road markings of Region Syd in Sweden in 2011.

VTI notat 8:2-2012 – Condition assessment of road markings of Region Väst in Sweden in 2011.

VTI notat 8:3-2012 – Condition assessment of road markings of Region Öst in Sweden in 2011.

VTI notat 8:4-2012 – Condition assessment of road markings of Region Stockholm in Sweden in 2011.

VTI notat 8:5-2012 – Condition assessment of road markings of Region Mitt in Sweden in 2011.

VTI notat 8:6-2012 – Condition assessment of road markings of Region Norr in Sweden in 2011
