The variables which describe a mass transit system are combined in a statistical model to produce a new set of mutually independent variables called principal components which also describe the system. The principal components are combined in a generalized n-dimensional model which in three dimensions is identical to the shear and normal stress on the octahedral plane, a well-known concept from engineering mechanics. The normal stress is a measure of the system's tendency to grow without structural change; the shear stress is a measure of the tendency to change structurally without growth. These stresses are compared with the energy and employment requirements and dollar of various bus systems.
