STRATIFICATION APPROACH TO EVALUATION OF URBAN TRANSIT PERFORMANCE

In a period of growing transit operating deficits, increasing attention and concern is being directed at both the decreasing levels of productivity of transit systems in general and the broad differences in measured service performance compiled for various transit systems. In making these performance assessments, analyses have commonly relied on highly aggregated industrywide data and have not given adequate consideration to the changing and unique operational context within which individual transit systems must function. This paper presents a stratification approach to the evaluation of urban bus transit system performance. The stratification scheme was used on the premise that there exist many environmental and policy factors outside the control of the transit operator that constrain the performance of the transit system. Factors such as area population, population density, union work rules, system configuration, fleet age, and operational forms have strong influences on the productivity and efficiency levels of an individual transit service. By implementing the stratification procedure and compiling temporal data pertaining to both environmental and policy influences and system performance, the possible bias in making assessments and comparisons of existing transit systems can be controlled, and changes in performance levels of a system in response to both external changes and operational improvements can be predicted.
