Objective Category
System Reliability: Travel Time 90th/95th Percentile

These objectives focus on reducing the 90th or 95th percentile travel time for one or more routes or trips in the region. The 90th or 95th percentile travel time represents one of the worst travel times for that route or trip because it indicates that 90 – 95 percent of travel times for that route are shorter than the 90th or 95th percentile travel time.

Associated Objectives and Performance Measures

Objective Performance Measure
Reduce the average of the 90th (or 95th) percentile travel times for (a group of specific travel routes or trips in the region) by X minutes in Y years. 95th or 90th percentile travel times for selected routes.
Reduce the 90th (or 95th) percentile travel times for each route selected by X percent over Y years. 95th or 90th percentile travel times for selected routes.

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.
