What is Transportation System Performance Measurement?
Performance measurement on a transportation system is the use of statistical evidence to determine progress toward specific defined transportation system objectives. It is important to help monitor the transportation system and use this information to decide on future enhancements to the system. Without knowing how the system is performing, it is impossible to get the best value for the money earmarked for system improvements.
What is performance management?

What does a typical definition of a measure include?
A specific goal or objective.
Data requirements (such as population, frequency of measurement, and data sources).
The calculation methodology (such as equations used and precise definition of terms).
Reports in which the data and a graphic presentation of the data will be used to report the data.
Any other relevant rationale for the measure.
What is a Performance Goal?
A performance goal is a target level of an activity (or outcome) expressed as a tangible measurable objective, against which actual achievement can be compared. Outcome activities for a transportation system would be mobility/accessibility, reliability, customer satisfaction, economic well-being, sustainability, environmental quality, safety and security, and equity.
