Pupil transportation: a cost analysis and predictive model

"School bus transportation is the only type of mass transit operating in all parts of the United States today. In many rural areas it is the only form of transportation available apart from the private automobile. In many urban areas the school transportation system rivals the municipal transit system in capacity, scope and budget. Despite the importance of the systems themselves, and the hints they might provide for the organization of transportation alternatives to the automobile in areas, particularly rural regions, where alternatives do not presently operate, there is a relative paucity of research on pupil transportation systems. This paper presents a study of such systems in Texas." -- Introduction
