Nevertheless, depending upon the specific indicator assessed, one can reach to different conclusions regarding performance. Furthermore, though performance and scale economies are closely related issues, they have been generally examined separately in the transit literature.
There have been significant amounts of research undertaken in order to examine the transit system performance, and in turn of assessing the performance based on such methods but the two characteristics underline the work. First, due to heterogeneity in getting different relationships between efficiency and effectiveness, system performance, existence of scale of economies and various such issues, the conclusion which have come out of different studies is not same. In other words there are conflicting conclusions. Even researchers are not using the data which is provided by NTD (National Transit Data base) and as a result the comparability of findings across researches is questionable. A second problem arises because researches have been using cross section-time series data from largely heterogeneous systems and have introduced a size-related bias in their results (Berechman, 1993).
Tomazinis (1977) specified a set of indicators in order to measure the public transit systems’s performance. His measurement was built on three bases;…
