Historically, transit management had to rely on a technique known as peer-group comparison to identify strengths and weaknesses in the performance of their system. In this technique, performance indicators for the system under study are compared with the average performance of systems that have similar characteristics. This method, though useful, is deficient in that it does not totally reflect the differences in operating characteristics or environment among transit properties. This paper presents a diagnostic tool for comparing performance among transit systems by suggesting a method to eliminate deficiencies in the traditional approach. The paper suggests that combined uncontrolled and controlled comparisons be used to identify relative strengths and weaknesses in performance. The uncontrolled comparison is the traditional approach in which system performance is compared with average performance of the peer systems. The controlled comparison is performed by comparing that actual performance with the expected performance. The expected performance is calculated from models that can be developed from the experience of the peer systems. This paper presents a case study in which uncontrolled and controlled comparison concepts were used to identify strengths and weaknesses of 11 bus depots in the New York City Transit Authority. The paper presents 10 transportation and maintenance performance indicator models that were used to calculate the expected depot performance. The models were developed through stepwise multiple regression analysis of the New York City Transit Authority's actual operating statistics for fiscal year 1977. The paper also discusses how the uncontrolled and controlled comparisons were subsequently used to set priorities among depots for remedial action. The application of the performance comparison technique discussed in this paper to smaller systems would require comparison of the system's performance with that of other similar transit properties.
