Procedures for the Prioritizing of Road Improvements under the Statewide Highway Plan

摘要

The road improvement prioritizing system currently utilized by the Virginia Department of Transportation is similar to the method utilized by many states: it is a sufficiency rating system that evaluates proposed projects on the basis of points assigned for a number of variables. In the report, an alternative method is introduced that consists of sorting projects in sequential ranking steps based on ranges of individual variables. The proposed method is simpler, more flexible, and requires less data manipulation than the present rating system. Individual variables have greater impact on the prioritizing process, and the resulting pr ioritizing ratings correlate well with results obtained from the previous rating method.
