This synthesis will be of interest to transit agency general managers, as well as to bus operations and maintenance personnel. It will also be of interest to equipment suppliers, consultants, and others concerned with bus maintenance operations. This synthesis describes current practices related to maintenance performance. The objective is to identify how maintenance performance measures drive day-to-day and strategic decisions. Administrators, practitioners, and researchers are continually faced with issues or problems on which there is much information, either in the form of reports or in terms of undocumented experience and practice. Unfortunately, this information often is scattered or not readily available in the literature, and, as a consequence, in seeking solutions, full information on what has been learned about an issue or problem is not assembled. Costly research findings may go unused, valuable experience may be overlooked, and full consideration may not be given to the available methods of solving or alleviating the issue or problem. In an effort to correct this situation, the Transit Cooperative Research Program (TCRP) Synthesis Project, carried out by the Transportation Research Board as the research agency, has the objective of reporting on common transit issues and problems and synthesizing available information. The synthesis reports from this endeavor constitute a TCRP publication series in which various forms of relevant information are assembled into single, concise documents pertaining to a specific problem or closely related issues. This report of the Transportation Research Board addresses traditional maintenance performance measures such as Section 15 indicators, as well as others used for decision making and those that affect customer service. These include, but are not limited to the ratio of scheduled versus unscheduled maintenance, customer marketing and employee opinion surveys, roadcalls, productive versus nonproductive time, causes for delay, product defects, and induced failures To develop this synthesis in a comprehensive manner and to ensure inclusion of significant knowledge, available information was assembled from numerous sources, including a number of public transportation agencies. A topic panel of experts in the subject area was established to guide the researchers in organizing and evaluating the collected data, and to review the final synthesis report. This synthesis is an immediately useful document that records practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As the processes of advancement continue, new knowledge can be expected to be added to that now at hand. (Author/publisher).
