An optimum allocation model has been utilized to examine the existing allocation of highway segments to maintenance garages in the Hamlin study area. The model has also been used to evaluate the financial effect of closing the garage at Hamlin. The examination of the study area shows that only three of 48 highway segments should be reallocated at an annual operational savings of approximately $1,400. The study concludes there would be an annual operational savings of approximately 128,700 if the garage at Hamlin were closed.

Highway maintenance engineers and administrators are often confronted with a number of problems related to highway maintenance work programs. One of these problems is concerned with determining the optimum number and locations of highway maintenance garages in a given area. Serious decline in highway revenues and a high inflation rate have made it necessary to examine existing maintenance practices and to allocate reduced financial resources more effectively and efficiently. Searching for and providing of reasonable solutions to these problems is the focus of this research project. The methodology used is to identify and modify for use (if necessary) those models which have already been developed. Models which could give optimum number and locations of highway maintenance garages were found to be too theoretical and/or practically infeasible. Consequently, research focus was shifted from these models to other models that could compare alternatives and select the best among these alternatives. Three such models -- the Alabama model, California model, and Louisiana model, were identified and studied.
