Abstract — The Real Time Bus Monitoring and Passenger Information bus tracking device is a standalone system designed to display the real-time locations of the buses in metropolitan city. This system will enable the tracking device to obtain GPS data of the bus locations, which will then be transferred to a centralized control unit by using GSM and then transmitted to a bus stop and displayed on the GLCD as per the passenger’s request. The existing systems find it inconvenient to reschedule their times in events of a vehicle break down and congestion of roads. This causes uncertainty to passengers about the arrival time of buses. But the proposed real time bus monitoring system can overcome these disadvantages of the already existing systems.
