由于需要衡量运输系统的绩效沿着其各个方面，因此制定了大量的量化绩效指标。然而，根据所审查的具体指标，往往可以就业绩得出不同的结论。此外，虽然业绩和规模经济是密切相关的问题，但在过境文献中一般都是分开审查的。本文采用数据拟合分析和全球有效前沿生产函数，研究了公交运营中的两个重要问题：第一，绩效的两个基本维度，即效率和有效性之间的关系;第二，绩效和规模经济之间的关系。使用来自美国256个交通系统的五年数据，结果表明，效率和有效性呈正相关。此外，他们意味着规模经济的大小取决于输出规格。
The need to measure transit system performance along with its various dimensions has led to the development of a large number of quantitative performance indicators. However, depending upon the specific indicator examined, different conclusions can oftentimes be reached regarding performance. Further, although performance and scale economies are closely related issues, they have been generally examined separately in the transit literature. The research reported in this paper uses data envelopment analysis and globally efficient frontier production functions to investigate two important issues in transit operations: first, the relationship between the two basic dimensions of performance, namely efficiency and effectiveness; second, the relationship between performance and scale economies. Using data from 256 US transit systems over a five-year period the results indicate that efficiency and effectiveness are positively related. Further, they imply that the magnitude of scale economies depends on the output specification.
