The potential danger: Poor quality <strong>of</strong> road on the territory <strong>of</strong> Serbia.Determining the likelihood <strong>of</strong> negative events:1. FREQUENCY:due to the bad roads, score <strong>of</strong> the accidents in the last 5 years is 10 - OCCASIONALLY oraproximately 50% <strong>of</strong> the highway through Serbia is <strong>of</strong> poor quality, therefore, the time exposure <strong>of</strong> theburden to the potential danger is about 50% <strong>of</strong> the total time <strong>of</strong> <strong>transport</strong> through Serbia –OCCASIONALLY;2. VULNERABILITY:Vehicles are equipped with electronic suspension control system by which shocks <strong>and</strong> movement <strong>of</strong> freight arereduced – SMALL.Using Form (1) <strong>and</strong> matrix 1., the determination is: PROBABILITY = 2 = UNLIKELY.Conclusion: The probability that the perceived danger is becoming a potential negative event is very small.3. CONSEQUENCES:Consequences (C) are (Matrix 2) the effects <strong>of</strong> the negative events on the protected values <strong>and</strong> are manifestedthrough the size <strong>of</strong> the loss in relation to the critical protected values 5) .Gradation <strong>of</strong> result is done as follows:1 - Minimal, 2 - Small, 3 - Moderate, 4 - Serious, 5 - CatastrophicConsequences are determined according to the form:C = L # Cr..................................................................................................................................................
