This document describes a passenger indicator system for buses that uses sensors and wireless communication to provide information to drivers. The system has two main modules: an in-bus module and a bus stop module. The in-bus module gives drivers information on whether passengers are waiting at upcoming stops so drivers know whether to stop or proceed directly to the next stop. It can also provide details on passenger destinations using GSM or Bluetooth technology. The system is intended to assist drivers and reduce unnecessary stops. It uses a PIC16F877A microcontroller and sensors to monitor passengers and communicate wirelessly. This type of monitoring system could benefit public transportation systems by facilitating real-time tracking of vehicles and stops.
