Transit reliability is critical to the operation and attractiveness of public transportation services. With the current unprecedented evolution in transportation services, including new competition from mobility service providers such as Uber and Lyft, improving transit reliability has taken on an even greater level of importance.

The TRB Transit Cooperative Research Program's TCRP Research Report 215: Minutes Matter: A Bus Transit Service Reliability Guidebook details eight steps that a transit agency can undertake to develop and maintain a Reliability Improvement Program.

There is also a Power Point presentation that provides an overview of the project accompanying the report and a supplemental report, TCRP Web-Only Document 72: Developing a Guide to Bus Transit Service Reliability.
