The performance of wet visibility road markings: final report on Provväg 1998-2000
2001 (English)Report (Other academic)
In a field test, the function of road markings, primarily with regard to their retroreflective properties in the wet state, was tested. A total of 39 road markings, visible in the wet, were studied on two test sections. Measurements of retroreflective properties (dry and wet), luminance coefficient and friction, and assessments of the state of wear, were made on four occasions over a two year period. A study was also made in a separate measurement series, in winter conditions, of the retroreflective properties of road markings on days determined in advance. In this way, weather conditions were random, and the results of these measurements may be said to represent the visibility of road markings on typical winter days in central Sweden. In the report, comparisons are also made between the function of road markings (their visibility in the dark) and the requirements which, according to COST 331, should be specified with reference to the needs of road users.
