摘要：	The report describes best practice guidelines for black spot management and network safety management with regard to classification of roadway elements, identification, accident analysis and evaluation of treatment. It is recommended that hazardous sites be identified by use of model based methods. The analysis should consist of a general accident analysis and a collision diagram, which are compared with the normal accident pattern for similar locations. A road inspection and relevant traffic and road analyses should also be made. It is important to assess if the identified sites are true hazardous sites. The evaluation should be made as a before-and-after-study controlling for long-term trends in the number of accidents, local changes in traffic volume and regression-to-the-mean by use of correction factors. / Availability Note: Product reproduced from digital image.
