This paper uses data of seventy-seven bus transit systems to develop an econometric cost model which is used to determine the productivities of labor, capital, fuel, total productivity and economies of scale. Statistical associations are then developed between these performance variations across transit systems. The results of the analysis show short run economies in transit operations, high labor productivity, and low fuel and capital productivity. The analysis also shows that the selected variables have different effects on the productivities of the various inputs. This suggests further analysis to determine possible tradeoffs between productivity losses of one input and productivity gains of other inputs. The outcome of the tradeoff analysis can be obtained from the signs of the coefficients in the regression equation showing a relationship between total productivity and the fourteen variables. The tradeoff analysis reveals that except for federal section 5 subsidies, local state and federal section 3 subsidies improve total productivity. These improvements can be traced to labor and fuel productivity in the case of local and federal section 3 subsidies. Thus, improvements in the productivities of fuel and labor are important in increasing transit total productivity.
