Abstract
Using only classical methods based on the calculation of objective statistical risk after the traffic accident expertise, it is very difficult to select the traffic accidents that were probably caused by fatigue of road vehicle drivers. The iRAP methodology can significantly assist in the selection of road traffic accidents which were probably caused by the driver's fatigue, because by using the iRAP methodology the static safety of road infrastructure elements can be quickly and objectively evaluated, and then excluded as a possible cause of a traffic accident. According to dynamic and open TCI Fuller's model “task demand - driver's capability”, drivers dominantly influence the desired level of task demand while driving by choosing the speed, which in the case of choosing the unacceptable speed or speed unsuited for the environmental conditions on the road, among the rest, may depend on whether the driver is under the influence of fatigue. On the example of six traffic accidents that occurred on motorways in the Republic of Croatia and were selected for statistical analysis by characteristic criteria from the recent scientific literature, it will be presented how by using the iRAP methodology the factors of road infrastructure from the group of “traffic environment” factors can be completely excluded as the cause of traffic accidents. The more accurate selection of road traffic accidents that were caused by driver’s fatigue will help researchers from other scientific fields to select and explore the characteristic factors of fatigue-related traffic accidents in order to suggest measures to reduce the fatigue effect on the driver's performance.
