RTD's OVERALL System Score
Excuse me...
How did you come up with your score?
Follow me...
I'll show you!
He may be right -
I still don't understand
the score...
Well... Let's walk
through the process
together.
Let's start with categories.
I like trains.
How are they scored?
Now let's look at
scoring a train.
What is a condition assessment?
How is consistency in ratings maintained?
What is a Life Rating?
How is age or mileage converted into a score?
The Physical Condition Assessment
SGR Category Scores
SubCategory Scores
"Calibration of inspectors"
Ratings Standards Libraries improve consistency in ratings
Asset Scores
What is an Element?
Element = System of Asset

Each Asset is broken out into Elements

Elements are each inspected for Condition

Elements are monitored for Performance



Each Element
has standards
and this
seems overly
complicated
Alright!
Now, what
about Performance?
Denver
already had
a system
Performance Metrics and Scores
Cost
Road Call
Frequency and Duration
PM / CM Incidents (count)
(Top Secret Innovation)
Under development
How were upper / lower limits established?

RTD had data on many of the metrics going
back to 2007.



We have assessment instruments.
Service Delay Score:

1.)
Used life

year of each vehicle.
2.)
Remaining Life

of Each vehicle.
3.)
Delay per mile
4.) Expected
Remaining Delay_Minutes / mile


5.)
Convert
to 0-5 SGR Score

Performance Rating

Everyone is familiar
with the age-based
approach.
Confidence in the Data
At each step along the way data must be validated and corrections made.

What is a Performance Rating?
What metrics are used?
How are scores determined?
How do other categories rate?
In addition to SGR score we also can plot trends over time allowing a shift from find and fix to predict and prevent.

Data should not be used for decisions or analysis
)
Method to express the level of certainty in data. 95% CI is the range that has a 95% chance of containing the correct answer. Should accurately reflect uncertainty about data.
Confidence Interval

This is true for all 3 pillars.

The Denver Method
Remember Me?

This is the Denver Method
It is available and transparent
It is scalable and modular
We are continuing to build out the program
RTD has realized cost savings
We can now make better information based decisions
We still face challenges
We have been successful because of
RTD defines Asset Management as:
“Transit asset management is a strategic and systematic process through which an organization procures, operates, maintains, rehabilitates, and replaces transit assets to manage their performance, risks, and costs over their life-cycle to provide safe, cost-effective, reliable service to current and future customers.”
State of Good Repair:
A balanced approach to measures of condition which are achieved when assets, infrastructure, systems and components are replaced or are functioning cost effectively relative to their designed purpose, current need, industry standards and evaluated against a specific list including...

Accidents; Service Delivery; In-service failures (road-call); Cost increase and PM vs CM - ratio
The
objective
of maintaining or achieving a State of good repair is to
reduce the frequency and severity of
a specific list of
undesirable events
including:

Accidents; In-Service delays; Cost increases and CM vs PM...
The idea is that
measures
should
increase value
or
reduce uncertainty, risk
or
impact

Improve or increase:
On time performance; Accident free miles traveled; Service delivery; Cost per mile; Ridership and Usefulness
