Objective Category
Freeway Management: Reliability

These objectives aim to reduce the variability in travel time on the freeway system so that users experience a more consistent and predictable trip time.

Associated Objectives and Performance Measures

Objective Performance Measure
Reduce buffer index on the freeway system during peak and off-peak periods by X percent in Y years. The buffer index (represents the extra time (buffer) travelers add to their average travel time when planning trips in order to arrive on-time 95 percent of the time).
Reduce delay associated with incidents on the freeway system by X percent by year Y. Hours of delay associated with incidents.
