16 3.1 Introduction This chapter details the steps that agencies can use to start and maintain a reliability improvement program. Although the focus of this work is on fixed-route bus services, the same process could easily be used for any mode of public transportation subject to similar delays in boarding, alighting, and travel time.

18 Minutes Matter: A Bus Transit Service Reliability Guidebook Similarly, an agency's capacity to gather data on customer perceptions and preferences can play a role in selecting measures of reliability. Developing the data needed to estimate customer travel times and wait times requires more extensive survey capabilities than do less customer-focused assessments of on-time performance and running times.

Therefore, the tasks described previously will be more extensive with a new comprehensive reliability improvement program.

Although backup detailed data may be provided, the reports should be easy to read and digest by decision makers within the agency, who will push reliability issues to the next step in the process: diagnostic assessment.

24 Minutes Matter: A Bus Transit Service Reliability Guidebook 3.7.1 Range in External Involvement with Treatments For the purposes of this guidebook, treatments have been grouped into four categories: operational, physical, technological, and policy-related. Operational treatments are those that agencies implement at the system, route, trip, or stop level through service planning and for realtime control.

Developing a Bus Service Reliability Improvement Program 25 Finally, the treatment trade-offs and expected effects should be considered to ensure that the treatment is an appropriate fit. The trade-offs in customer impact, community impact, or necessary changes or training within the agency may not be acceptable in exchange for the expected effect on reliability.

26 Minutes Matter: A Bus Transit Service Reliability Guidebook Although such outside coordination can make implementing treatments more time-consuming and costly, with good ongoing relationships between agencies, such efforts can be much easier and may be less costly than some technological treatments that require substantial equipment cost.
