Development of Transit System Productivity Measures Based on Section 15 and Urban Area Environment Data

摘要

The study examined the relationships among measures of transit system productivity, the characteristics of transit systems, and the characteristics of the specific geographic areas where transit system services were provided. The data set consisted of the 34 transit systems in the southeastern federal region that operated exclusively in the bus mode during the 1979-80 fiscal year. Two different techniques were used to examine possible relationships among the data. The first technique employed the traditional statistical analyses of correlation and regression. The second technique, Automatic Interaction Detection (AID), did not surface in the literature review as having been used before in a similar research application. Because of this unique application of AID, this study examines its potential for identifying and explaining the structure of transit productivity.
