Operator Overlap population

The dynamics behind this phenomenon can profitably be used for the development of accident countermeasures in the form of positive incentives for accident-free operation (which consequently strengthen utility factor 3 , the perceived benefits of choosing cautious behaviour alternatives). Much of the evidence comes from occupational experience, while other studies relate to road use in the general population. That there is considerable overlap between these two domains is highlighted by the fact that, when commuting is included, more than half of some half a million occupational fatalities worldwide occur on the roads (Takala, 1999).
