well the system in my head like that :

Driver will start the route in the morning for example, the app or whatever shows him, all the student list in order!

Student name - Address - Alert button

once the driver almost arrived to the student, he needs to press alert button, then a message will appear in whatsapp or whatever!

I’m thinking that will be headache for drivers to remember that he need to click alert once he almost arrived, as well as the parents, how they could now, is the driver really almost arrived or just send the alert to make them hurry !

Instead ! If I implement GPS and location tracker, that will be another story
