IOT Based Smart Bus Tracking and Passenger Information System Using RF Communication

The rapid growth of urbanization has increased the demand for efficient and intelligent transportation systems. This paper presents a Bus Tracking System using RF Communication integrated with the Internet of Things (IoT) to provide real-time passenger information. The system utilizes RF modules for short-range communication between bus units and bus stops, while IoT ensures remote monitoring through cloud platforms. RF transmitters installed in buses are detected by receivers at bus stops to identify arrival and departure. The collected data is transmitted to a centralized IoT platform via a microcontroller for processing and display on web or mobile applications. The implementation demonstrates a cost-effective, scalable, and reliable solution that minimizes passenger waiting time and improves operational efficiency.
