Design elements - Fault tree analysis diagrams

The vector stencils library "Fault tree analysis diagrams" contains 12 symbols for drawing Fault Tree Analysis (FTA) diagrams.
"Fault tree analysis (FTA) is a top down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events. This analysis method is mainly used in the fields of safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk or to determine (or get a feeling for) event rates of a safety accident or a particular system level (functional) failure. FTA is used in the aerospace, nuclear power, chemical and process, pharmaceutical, petrochemical and other high-hazard industries; but is also used in fields as diverse as risk factor identification relating to social service system failure.
In aerospace, the more general term "system Failure Condition" is used for the "undesired state" / Top event of the fault tree. These conditions are classified by the severity of their effects. The most severe conditions require the most extensive fault tree analysis. These "system Failure Conditions" and their classification are often previously determined in the functional Hazard analysis." [Fault tree analysis. Wikipedia]

This arrow loop diagram sample was created on the base of the figure illustrating the webpage "Safe Roads for a Safer Future A Joint Safety Strategic Plan" from the website of US Department of Transportation - Federal Highway Administration (FHWA) Office of Safety.
"STRATEGIC PLANNING CYCLE.
After the safety units issue the SSP, they will identify and prioritize strategies to support the established goals. Many strategies will originate in existing roadmaps or in other program planning activities. The safety units will also use this information when developing their Unit Performance Plans and individual performance plans. Teams within each safety unit will carry out projects and activities to support identified strategies and achieve the SSP goals.
The SSP process also includes continuous performance monitoring and evaluation through which the safety units will review past accomplishments against the established goals, consider how well strategies are implemented, assess progress toward goals, identify risks, consider changes in the environment, and discuss future strategic direction. As a part of the evaluation process, the three safety units will recognize achievements and discuss the need for adjustments. Figure ... shows the strategic planning cycle.
The safety units will update the SSP every 3 to 5 years using input from a variety of sources, including evaluations, safety trends, and legislative changes." [safety.fhwa.dot.gov/ ssp/ ]

This Venn diagram sample shows the significant characteristics of pedestrian crashes. It was designed on the base of the Venn diagram in the "Pedestrian Safety Strategic Plan: Recommendations for Research and Product Development" from the website of the Federal Highway Administration of the U.S. Department of Transportation.

"Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, and passengers of on-road public transport (mainly buses and trams).
Best-practices in modern road safety strategies focus on preventing serious injury and death from vehicle crashes despite human fallibility." [Road traffic safety. Wikipedia]
