2
2 Agenda Welcome Back & Meeting Objectives Meeting #1 Recap Draft Performance Measures Group Work Session Wrap-Up
3
Meeting Objectives Recap Meeting #1 – Examples, baseline needs, “Dot” exercise Confirm needs for TSMO metrics Build requirements & implementation plan for metrics – Actionable plan – how & when? Identify outstanding items to address in plan 3
4
Meeting #1 Recap 4
5
“System Management” Definition Performance Measures Related to… Freeway Management (excl. TIM) Arterial Management (incl. signals) Mobility & Reliability Asset Management 5
6
Lit Review Recap Recommendations – Desired outcomes should drive perf. meas. – Keep it simple – Useful metrics to wide audiences – Use well-defined metrics – Data quality – Data fusion and automation 6
7
Lit Review Recap National examples including 7

Meeting #1 Dot Exercise Results High importance (Mobility – Freeway and Arterial) – Volume – Travel time – Congestion – Planning time index (reliability) – Delay High importance (Asset) – Inventory – Condition rating 10

Meeting #1 Action Items Send ideas or comments on PMs to Chris Use the forum tab on the project website for discussions – http://sites.kittelson.com/TSMOPM/Forums http://sites.kittelson.com/TSMOPM/Forums Kittelson to combine information and rankings collected through the small group activity and dot exercise 11

14
Example Performance Metrics per Category 14 Specific performance measure to be evaluated Has specified units
15
Existing? 15 Does ODOT already collect data or report on this metric? – Yes, No, or In-Process
16
Data source / input requirements 16 What information is needed to evaluate and report on this metric?
17
Issues Addressed, Sensitivity trying to capture 17 Why evaluate this metric?
18
Freeway vs. Arterial 18
19
Importance 19 Relative importance – Ranked high, med, or low Will influence… – which metrics go into the plan & – order of implementation
20
Data easily available? 20 Ease of accessibility and use of source data for metric? – Ranked high, med, or low
21
21 Group Discussion/Feedback Is the measure clear & understandable? Does ODOT have the needed data? How will the perf. meas. be actionable? Are perf. meas. missing from the list? Implementation? How would you prioritize them?

Asset Management 32
33
Recommended Asset Mgmt. Condition Rating Score each individual device on each performance measure, normalized by 0 to 100. – Lowest = worst, Highest = best Performance Measures: – % of design life remaining – Resources spent on asset (hard & soft costs) % proactive vs. % reactive – % of asset downtime Device Communication Supporting System (e.g. Detection) 33
34
Define Targets for Asset Management Expected service/design life. – Target of full design life per device/system. – No device exceeding 100% of design life. Expected annual O&M cost by device type. – 70% of O&M costs are proactive 100% uptime target (0% downtime target). – What’s realistic per device/system? 34
