Travel Time Index (TTI)The Travel Time Index is the ratio of the peak-period travel time to the free-flow travel time.
Planning Time Index (PI)The planning time index represents how much total time a traveler should allow to ensure on-time arrival. It is the ratio of the peak-period travel time to the free-flow travel time.
Buffer Index (BI)The buffer index represents the extra time (or time cushion) that travelers must add to their average travel time when planning trips to ensure on-time arrival.
