SYSTEM ANALYSIS OF OBSTRUCTIVE BRIDGES

In 1966 the U.S. Coast Guard took over various bridge functions from the Corps of Engineers and one of these functions is the program of altering bridges that obstruct navigable waters. This program requires the Commandant to make a determination if a bridge is an unreasonable obstruction to navigation before he can proceed to have it altered. The primary purpose of this study is to develop criteria that can be used for that determination. A system analysis will be developed where the relevant factors are modeled. A ranking criteria will be established within a decision framework to permit the determination of obstructiveness. This same model can then be used to rank all new cases in order to establish priorities for the Planning, Programming and Budgeting System by updating specific data inputs.
