Conclusion
Properly used, CAPTool allows users to compare multiple modes of transportation assets on
a common basis. CAPTool identifies assets and asset classes that are of highest consequence and
thus most important to the functionality of the transportation mission. CAPTool provides an
effective means to analyze assets in an objective, transparent manner.
CAPTool results depend upon the quality of the information and judgments used in applying
it. Missing or unsubstantiated data concerning asset characteristics--such as length, cost, and
usage--skew results inappropriately. Inconsistent input data also cause assets to be identified as
more or less consequential than they should be. Efforts should be made to ensure consistent
inputs to the CAPTool.
CAPTool is designed to be iterative. Users can apply different consequence thresholds to assets
and consider various countermeasures. CAPTool is more effective when the user alters thresh-
olds and reviews results of these scenarios. This iterative process allows the user to determine the
assets of highest consequence for further evaluation. CAPTool makes the iterative process easy
by supplying informative summary reports that allow a decision maker to choose between dif-
ferent threshold settings and countermeasure selections.
CAPTool provides a summary report designed for submission and presentation to decision
makers. The summary report, displayed at the end of CAPTool, provides the thresholds chosen,
results, and allocation of resources by mode. Various iterations of consequence threshold and
countermeasures can be chosen and summarized, such that a range of alternatives can be dis-
played. This iterative approach allows the decision maker to make the best decision.
The Basic CAPTool is designed to suit the needs of a majority of transportation officials. The
embedded equations and data are drawn from practical experience, and engineering judgments.
Costs are based on national averages. The CAPTool recognizes that transportation agencies
have access to data and resources to identify costs applicable to the area and assets of interest.
The Enhanced CAPTool allows the user to alter costs and to apply countermeasure screening
judgments.
Used properly, the CAPTool provides decision support to the difficult task of resource allo-
cation across multiple modes. CAPTA combines a transparent means to capture management
judgments on consequence thresholds with the objective characteristics of the assets analyzed to
produce a list of high-consequence assets that merit further examination. CAPTool identifies
high-consequence assets and links them to objective data and user choices.
