<p>The HazardousEvent metaclass represents a combination of a Hazard and a specific situation, the latter being characterized by operating mode and operational situation in terms of a particular use case, environment and traffic. <br/></p><p><br/></p><p>Semantics:<br/></p><p>The HazardousEvent denotes a combination of a Hazard and an operational situation. The controllability and severity attributes shall be consistent with the operational situation and operational scenario, and the Exposure shall reflect the likelihood of the operational situation and scenario.<br/></p><p><br/></p><p>Notation:<br/></p><p>The HazardousEvent is shown as a solid-outline rectangle with "Haz" at the top right. It contains the name of the HazardousEvent and optionally the name of the source entity.<br/></p><p><br/></p><p>Extension: <br/></p><p>UML::Class<br/></p>
