What Is Transportation Performance
Management?
FHWA defines Transportation Performance
Management as a strategic approach that uses
system information to make investment and
policy decisions to achieve national performance
goals.
National Performance Goals

Congestion Reduction
System Reliability
Freight Movement and Economic Vitality
Environmental Sustainability

Top 10 Reasons for Performance
Measurement System
It improves the bottom line
Allows an agency to align its strategic activities
to the strategic plan.
Measurement
It allows managers to identify best practices
Supports better and faster budget decisions

US Federal agency are required by law.
It can raise an agency's long-term chances of survival.
Performance Measurement history
from Wikipedia Performance measurements (PM) were developed In 1943
During The Kennedy administration, The Department of Defense started using PM
Other Federal agencies began experimenting in PM during the Johnson administration.
Eventually more and more state and local governments began using performance measurement to improve their management and budgeting.
The use of performance measurement became a common practice in the 1970s.
PM popularity die out in the 1980’s
PM started making a comeback in the 1990’s
Top 10 Reasons for Performance
Measurement System It improves the bottom line by reducing process cost and improving productivity and
mission effectiveness
A performance measurement system such as the Balanced Scorecard allows an agency to align its strategic activities to the strategic plan. It permits -- often for the first time -- real deployment and implementation of the strategy on a continuous basis. With it, an agency can get feedback needed to guide the planning efforts. Without it, an agency is 'flying blind'.
Measurement of process efficiency provides a rational basis for selecting what business process improvements to make first.
It allows managers to identify best practices in an organization and expand their usage elsewhere.
The visibility provided by a measurement system supports better and faster budget decisions and control of processes in the organization. This means it can reduce risk.
In short, Transportation Performance
Management: Is systematically applied, a regular ongoing process
Provides key information to help decision makers allowing them to understand the consequences of investment decisions across transportation assets or modes
Improving communications between decision makers, stakeholders and the traveling public.
Ensuring targets and measures are developed in cooperative partnerships and based on data and objective information
Visibility provides accountability and incentives based on real data, not anecdotes and subjective judgements. This serves for reinforcement and the motivation that comes from competition.
7. It permits benchmarking of process performance against outside organizations.
8. Collection of process cost data for many past projects allows us to learn how to estimate costs more accurately for future projects.
9. If you are in a US Federal agency, it's the law. The Government Performance and Results Act of 1993 requires a strategic plan, and a method of measuring the performance of strategic initiatives.
10. It can raise you agency's Baldrige score, which can serve to increase its long-term chances of survival.

Travel Time Reliability
the consistency or dependability in travel times,
as measured from day-to-day and/or across
different times of the day.
Travel Time Reliability-Wikipedia
has been increasingly recognized as a key performance indicator for transportation roadways and transport systems. This has stimulated research into the development of measures to quantify the level of reliability or the extent of variability in travel times. As a result, several travel time reliability measures have been introduced over the last two decades.
