This article considers that the pre-schooler special-purpose school bus market potential is huge, after the analysis of the present situation of pre-schooler education in our country and pre-schooler school bus accidents in partial provinces and cities during 2005～2007. The security situation of school buses is unoptimistic. From the perspective of security, the complete form of the pre-schooler special-purpose school bus is reqestted on the basic of study of the school buses security measure in home and abroad. According to the statistical analysis of the human body size related to 3～6 year-old pre-schooler, the child chair's 6 main parameters, the passenger gate steps, and arm rest's size, as well as crossing control arm's mounting height and performance requirement have been determined. According to the present domestic and outside related standards to exports to the bus and school bus, the least quantities and most light-sized of the exports of school bus are proposed. According to the present domestic and outside standards to the request of driver's field of vision of bus and school bus, the essential requirements and inspection procedure of the field of vision of the pre-schooler special-purpose school bus are setted.
