TYPOLOGY FOR BUS TRANSIT.

Peer groups of similar transit systems are needed for comparative analysis of transit performance and facilitation of econometric analysis. Cluster analysis was used to construct 12 peer groups based upon size, average speed and peak-to-base ratios of urban, fixed-route motor bus transit systems. Analysis of variance, discriminant analysis and a decision tree typology confirmed differences in operating characteristics among the peer groups. The peer groups were also found to be significantly different on seven variables representing the major dimensions of transit performance. Performance are given for each peer group, and suggestions are made for using the peer groups in performance evaluations.
