Sažetak
Targets formulated in 64/255 resolution of the UN General Assembly and set for implementation in the period 2011 to 2020 stress as priority the prevention of accidents and road traffic safety to save millions of lives. The same targets have also been set by the EU and are to be implemented in the coming decade. One of the proposed measures to achieve these targets is by way of implementing the power model, as it shows direct relation between the speed of traffic flow and the number of road accidents and injured persons. Reliability of this model has been affirmed by several studies. It is simple to use and with certain adjustments may be applied to all road categories if relevant data on the number of traffic accidents and their consequences are available. Presented in the paper is the mathematical formulation of the model comprised of six equations that are to be used to analyze and determine the number of accidents with mortality, number of accidents with severely injured persons and number of accidents with injured persons, as well as the number of dead, severely injured and injured persons. In addition, a concrete example is presented of the assessed reduction of road accidents and the number of injured persons for planned speed reductions with significant increase in safety.
