THOSE RESPONSIBLE for the administration of pupil transportation are able to take advantage of the extensive amount of research relating to automotive equipment. The study and development in this field, for the improvement of motor vehicles generally, is directly useful in the manufacture of school bus equipment and is instrumental in the production of safer, more efficient, and more economical motor vehicles for the comfortable transportation of school children. No attempt will be made here to cite the extensive research relating to the development of automotive equipment; such research can be found in publications prepared for chassis and body manufacturers. This review will, however, touch upon that research which relates more specifically to the use of motor vehicles in the transportation of pupils. Bulletins relating to pupil transportation service have been prepared and printed in most of the forty-eight states. The material has usually been assembled by some one in the state department of education and frequently chapters are included which relate to equipment. In these chapters many opinions and recommendations are expressed, but there is little evidence to show that these are based upon facts. Absence of extensive research in this field is due more to the fact that findings have not been printed rather than to the lack of interest in school bus equipment. For instance, at Ohio State University alone, approximately thirty masters' theses have been prepared in the field of pupil transportation. It is recognized that an extensive amount of research on school buses may not be necessary since the ready-made equipment is available to school authorities, having been developed through careful and technical research on the part of engineers. From this point of view those interested in schools are in the fortunate position of having the work done for them by the motor vehicle industry. It is believed, however, that much more research than is available should be carried on by those interested in pupil transportation to determine the relationships existing between the various characteristics of school bus equipment and satisfactory school bus service.
