SIMPLIFIED PROCEDURES FOR DETERMINING COUNTY ROAD PROJECT PRIORITIES

Although more and more counties are realizing the value of systematic procedures to evaluate the condition of their highway networks and to establish priorities for candidate road projects, many of them are finding that they lack the data, background, and budget to implement a more comprehensive pavement management system (PMS). This paper reports the experiences of a county with a large network and a small budget, and its desire to implement a needs and priority-setting process that is fair, data efficient, and easy for any interested citizen to understand. Three simplified ranking procedures were developed or adopted: the index method, percentile method, and successive-subsetting method. Each method embodied a different combination of strengths and weaknesses, which gave them considerable value when used as a group. There was also remarkable agreement among the three methods when applied to the large, actual database. Not only are the three methods capable of working well with sparse data, they can be and have been used to direct the data collection efforts of a county that lacks up-to-date data. Two more sophisticated multicriteria ranking or optimization techniques were adapted to this problem for comparison with the three simplified methods, but the results did not justify the extra complexity of analysis. Finally, the value of the three simplified methods as steppingstones to multiyear PMS approaches is pointed out.
