Quantitative evaluation of the condition of assets
Should be analyzed and used to reallocate resources and funding to meet your asset management goals

TDOT uses a condition assessment program called the Maintenance Rating Index (MRI)
Random sample of roadway network
Approximately 6% of roadway miles evaluated each year
7,107 1/10th mile segments assessed in FY 2010

Asset Inventory
Evaluates all roadway characteristics monthly
Each characteristic has weighting factor used to generate a score
Pass/Fail based on whether it meets the minimum condition standard
Score from 0 to 100Target score is 90

10% of segments evaluated by third party consultant for quality assurance
In-house scores ~ 90QA scores ~ 82Red trend line should
match up to black line if QA & In-house scores were similar
Red line shift indicates higher In-house scores
Concentration of points with In-House score of 100 & QA score considerably lower is a concern In-House vs. QA

Condition AssessmentStrengths WeaknessesSatisfies GASB 34
requirementQuantitative evaluation
instead of subjective opinion
Provides for opportunity to find deficiencies that windshield inspection may miss
Data indicates that In-House self-evaluation has lead to elevated scores
May need to consider using impartial third party to perform inspections in the future
