__Figure 19: Distribution of Sensitivities for Requirement
23: Passenger Loading Zones. NPV = 1,835.3__

This figure is a bar graph showing the
distribution of sensitivities for the requirement relating to passenger loading
zones (Requirement #23). The *x* axis is labeled "Correlation of
Coefficients" and has a scale running from negative .1 to positive 1 in .2
increments. The *y* axis identifies the five key variables that have the most
impact on the risk range for the NPV of this requirement. These variables are
listed on the *y* axis from top to bottom in descending order based on the
size of their respective correlation coefficients. The graph shows that the
four variables have the following correlation coefficients: Likelihood of
Benefiting (0.724); Likelihood of Occurrence (0.412); Frequency of use (0.393);
and Access time savings (-0.238).
