Assessment Of Retaining Levels Of Safety Barriers

Abstract
Thousands of human lives are annually lost on European roads including the
Czech Republic. The main risk associated with the car collisions is the harm to
people traveling in the vehicle or to people in the road surroundings. It follows
that the main priority in performing risk analysis is to minimize this risk. In order
to determine the potential costs due to casualties in car accidents, the concepts of
the Implied Costs of Averting Fatality (ICAF) and Life Quality Index (LQI) are
applied.
It is shown that current standards do not provide sufficient information for
the optimal decision about the retaining capacity of road safety barriers close to
the resources of drinking water, railways, roads and other hazardous types of
road surroundings. The Bayesian network method is applied representing a
suitable tool for risk analysis in accidental design situations.
The objective of submitted risk assessment is to optimize the selection of the
retaining levels of safety barriers taking into account different categories of roads
and bridge surroundings.
Keywords: safety barriers, retaining level, categories of roads, risk assessment.
