Abstract
In this paper, to prevent accidents of school vehicles used by students, which have emerged as a continuous social problem, a
boarding and leaving notification system using Bluetooth beacons is proposed. The platform structure uses Bluetooth, a
smartphone, and an application, and provides real-time message reception between parents and teachers. It is not simply a
system with Bluetooth capability alone, but also an IcT technology that is closely related to real life using two-way
communication. The purpose is to provide user-friendly ICT technology as an integrated system for more practical effects. Two-
way exchange of information between parents and teachers using cloud servers is made possible. By using this Bluetooth beacon
notification system, safety accidents in student vehicles are reduced, which brings confidence from traffic accidents to
schoolchildren of parents and teachers. Therefore, it is expected that parents and teachers are expected to improve their mental
stability and quality of life from traffic accidents.

efficiencies than other technologies, provide real-time deliv-

technologies in nurturing talent, and the use of Bluetooth
signals as technical contributions provides options for utilizing
Bluetooth functions in various fields as well as commuting.
