Subject(s): Online resources: Bibl.nr: VTI P4477:740Location: Abstract: The relationship between speed and road safety is a controversial topic. In this report, the relationship between speed and road safety has been evaluated by means of a meta-analysis of studies that provide estimates of how changes in speed affect the number of road accidents and the number and severity of injuries to road users. This study was designed to evaluate the Power Model of the relationship between speed and road safety. This model has been proposed by the Swedish road safety researcher Göran Nilsson. According to the Power Model, the effects of changes in speed on the number of accidents and the severity of injuries can be estimated by means of a set of power functions.
