The Transit Capacity and Quality of Service Manual (TCQSM) provides transit agencies with tools for measuring their systems performance in different levels of operation. Bus service reliability as one of the key performance measures has become a major concern of both transit operators and users because it significantly affects users’ experience and service quality perceptions. The objective of this paper is to assess the existing reliability measures proposed by TCQSM and develop new reliability measures at the stop level. Utilizing empirical data from archived Bus Dispatch System (BDS) data in Portland, Oregon, a number of key characteristics of distributions of delay and headway deviation are identified and three new reliability measures at the stop level are proposed. The results of this study can be implemented in transit operations for use in improving schedules and operations strategies. Also transit agencies can use the proposed reliability measures in order to evaluate and prioritize stops for operational improvement purposes.
