The report discusses the development of a numerical quality scoring system for road safety evaluation studies. Previous research related to quality assessment of scientific studies is reviewed, but it is concluded that this research offers few guidelines with respect to quality scoring of road safety evaluation studies. A quality scale is nevertheless proposed and tested on a few road safety evaluation studies. / Availability Note: Product reproduced from digital image.
