The authors summarize and extend the existing frontier literature by outlining proper ways of decomposing efficiency using both radial and nonradial efficiency measures when using nonparametric, deterministic frontier models. This contribution relates to a recent paper of Viton (Transportation Research-B 31, 23-29, 1997) analyzing the efficiency of U.S. multi-mode bus transit systems. In particular, the author evaluates the technical efficiency, congestion and scale properties of these companies. Due to a methodological mistake he could not detect congestion in the sample. The authors' proposals remedy this problem and focus on the under-explored issue of proper congestion measurement in general and in transport in particular.
