An loT$-$based Smart School Bus System is a cutting$-$edge solution that can enhance the safety, security, and efficiency of school bus transportation. The system can incorporate various sensors$,$ actuators, and cloud technologies to provide a range of features and benefits. Imagine a typical morning at a school. The school buses are lined up outside, ready to take students to their respective schools. As the children board the bus, they swipe their school ID cards, and to make sure take their fingerprints which are connected to the cloud$-$based system. The system immediately registers the student's presence and sends an alert to the school and parents, notifying them that the child is on board wit its location, time, and date. Inside the bus, there are several sensors installed that can detect and report any unusual activity or behavior. For example, a camera mounted on the ceiling can monitor the driver's behavior to ensure safe driving practices. Additionally, the camera can also detect any suspicious activity or bullying among the students and notify the school authorities in real time. many other cameras for road monitoring. There is a laser sensor to monitor the windows of the bus. Another sensor that can be installed is the seat occupancy sensor$.$ This sensor can detect if a child is left behind on the bus after all the other students have disembarked. If this happens, the sensor can send an alert to the school and parents to ensure the child's safety. Furthermore, the Smart School Bus System can also incorporate GPS sensors that can track the location of the bus in real time. Parents can use an app or web portal to track the bus' ocation, and estimated arrival time, and even receive real$-$time notifications on the progress of the journey. The system can also include actuators, such as automatic stop$-$arm extenders and warning lights. These can be activated when the bus stops to pick up or drop off students, ensuring the safety of the children crossing the street. All the data collected by the various sensors and devices can be sent to the cloud for storage and analysis. School authorities can use this data to optimize routes, identify and address safety concerns, and provide a more efficient and secure transportation service. In summary, an loT$-$based Smart School Bus System can provide enhanced safety, security, and efficiency for school bus transportation.
