| Today, school buses transport millions of students to and from schools. Therefore, the safety of school students is still a hot topic and the most imperative issue. The evolution of wireless location-based services has created consumer requests for the availability of global positioning systems (GPS) in urban and indoor environments. Nowadays, there is a requirement to improve a monitoring system for the school bus, that monitors its location and speed. This work investigates two different ways to track the vehicle through ordinary GPS or Assisted-GPS (A-GPS). A-GPS improves startup performance (time-to-first-fix (TTFF)), of a GPS satellite-based positioning system in the downtown of big cities depending on 4G/LTE cellular networks. The proposed system is basically built using Raspberry Pi (3) with 4G model shield and important telematics technologies like Representational state transfer (RESTful API) which is the vital key for the Internet of Things (IoT) field. |
