The Washington State pavement management system (WSPMS) has a long and well-known history of describing network condition, predicting necessary rehabilitation, and guiding the Washington State Department of Transportation (DOT) to the best possible value for pavements meeting an acceptable level of service. By definition, lowest life-cycle cost (LLCC) is the most economical way to manage roadways to a required level of service. What does an agency do when it is currently, and projected to be, funded at less than half of what LLCC calculations recommend? This deceptively difficult question reflects the situation that the Washington State DOT currently faces with its preservation budget. To assist the agency in answering this question, the WSPMS developed a tool called the Forecaster, allowing definition of a forecast scenario that enables the user to define a yearly budget with optional allocations, preservation techniques, prioritization of roadways and activities, and more, and analyzes the results of the forecast by using several different performance measures. Presented are an overview of the new WSPMS tool to create forecasts, a general overview of the forecast process, and the performance measures that the WSPMS gives to users to analyze the results of a forecast. Finally, several funding scenarios are compared by the expected performance measure outcomes, and a specific prioritization methodology is recommended for the severely constrained preservation budget of the Washington State DOT.
