Abstract

This study describes an evaluation of the Ecodyn 30. The instrument has been studied with regard to validity, reliability, functionality and cost-effectiveness. In the study, measuring data from the Ecodyn 30 have been compared with data from the LTL2000. Models have been found for using retroreflection values measured with the Ecodyn 30 to predict values that would be obtained with the LTL2000. The report also contains proposals for modifying the Ecodyn 30 and some general views on the instrument. (A) A Swedish and English version is also available (VTI rapport 444 and 444A).
