School bus is the largest and safest transportati on system, and the research on it is increasingly deepening and specific. The review of the frontier studies on school bus in US shows that the traditional school bus safety issue still remains a concern among the come the priority of research, the research on w researchers, but problems related to school bus pollution has be- alking school bus is getting momentum, and route design based on computational modeling arouses the attention of researchers. On the basis of the above analysis, the paper proposes several suggestions to the development of school bus in China.%通过对2000年以来美国校车研究的前沿问题进行综述，发现虽然传统的校车安全问题依然为研究者所关注，但校车污染相关问题已经成为研究的首要领域，“步行校车”研究方兴未艾，基于计算模型的校车线路设计也开始引起研究者的重视。本文在梳理归纳的基础上提出了未来我国校车发展的建议。
