This manual is based on the well known CSIR Technical manual K21, published in 19762. Although a much more simplified approach towards the identification of hazardous locations, and step-by-step procedures regarding the investigation of such sites as well as determining the benefit / cost ratio's of possible improvements are given in this manual, much of the information contained in the original manual is repeated in this document. To assist the user, a list of collision patterns, their probable causes and general countermeasures are given. Furthermore the improvements recommended for various types of collision are described and an estimate is given of the degree to which these improvements could reduce collisions. Also included are updated collision costs and unit costs of road safety improvements as well as an example of the calculations regarding the analysis of a hazardous locationenHazardous locationsEliminationRoad safetyRemedial measuresK21National Department of TransportSouth AfricaReportOpperman, R., & Upton, A.
