Development of Transit Bus Component Failure Statistics from Conventional Bus Card Records

摘要

The purpose of the study is to demonstrate the feasibility and utility of determining the probabilities of failure for various major bus components and systems from existing maintenance records. The process for determining the failure probability distributions is demonstrated using maintenance data from the Alameda-Contra Costa Transit District (AC Transit). This process is applicable at other systems where maintenance records are available. The report discusses the development of the data base, the process of analyzing the data,and presents the results and conclusions. Standard bus maintenance record-keeping procedures are compatible with the requirements of reliability analysis techniques.
