Level of Service
Defines the amount of maintenance required to manage assets at a specified level
Should be supported at all levels of management within the agency
TDOT needs to tie Level of Service to the Condition Assessment to ensure that appropriate funding and resources are allocated to achieve target goals

Level of Service
Percent of assets maintained per year to achieve desired service level
Example:
Percent of signs replaced
Percent of pavement miles resurfaced

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

Condition Assessment
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 100
Target score is 90

10% of segments evaluated by third party consultant for quality assurance
In-house scores ~ 90
QA scores ~ 82
Red 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 Score

Weaknesses
Satisfies GASB 34 requirement
Quantitative 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
