Figure 18: Distribution of Sensitivities for Requirement 26: Passenger Loading Zones (Medical / Long-Term Care). NPV = -489.0

            This figure is a bar graph showing the distribution of sensitivities for the requirement relating to passenger loading zone at medical and long-term care facilities (Requirement #26).  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 five variables have the following correlation coefficients: Access time savings (-0.62); Frequency of use (-0.549); Likelihood of Benefiting (-0.398); Likelihood of Occurrence (- 0.133); and Alterations cost (0.111).
