Application of GNSS in School Bus Safety Monitoring

With the “Regulations of the School Bus Safety (draft)” issued by the State Council at the end of 2011, the management of school bus safety transportation has become a hot topic. This article puts forward a method of using Global Navigation Satellite System (GNSS) to monitor the school bus safety. The school bus transport and management system, which is real-time, accurate and efficient, will be built up by integrate satellite positioning technology, information technology, data transmission technology, electronic sensor technology, information processing technology and emergency services effectively. Firstly, the difference between the school bus monitoring and general vehicle monitoring is pointed out. Meanwhile, we find out the main reason is overload of passengers which cause the phenomenon of frequent school bus accident in recently. Secondly, a School Bus Overloading Monitoring System (School-Bus-OMS) is designed to prevent the phenomenon of overload of passengers. After that, the school bus safety monitoring system which based on GNSS and School-Bus-OMS is proposed. Finally, a detailed description on the structure, function and rescuing measures of this system are given, and the corresponding mathematical models are established.
