System Reliability: Planning Time Index
Objectives in the area of travel time reliability aim to reduce the variability in travel time so that transportation system users experience a consistent and predictable trip time. Unexpected delay is reduced for people and goods. This category focuses on the planning time index. This reflects the amount of extra time that travelers need to add to free-flow (or posted speed limit) travel time in order to arrive on-time in almost all situations. The planning time index takes into account both recurring and non-recurring sources of delay.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.
