WYDOT Asset Management Program Strategic Decisions Project Optimization Transportation Build Check STIP Development • Combine Projects • Phase Projects • Synergistic Efficiencies • Find Savings Opportunities • Project Prioritization • Project Shuffling • 6-Year Plan • 20-Year Plan Program Performance Measure Development Budget Constrained Tradeoff Analysis Development Program Performance Target Development
Asset Program Publishes “Candidate List” • Break out by treatment strategy • Break out by district • Multiple years gives flexibility for mobility, work load, politics, etc.
Trying for Different MeasuresTrack miles of treatment type and system type.
Pavement Condition – Preserving the good We can preserve, we just can’t fix!
