Predicting the Bus Arrival Time Using GPS and GSM Technology

The primary information to most city transport travelers is bus arrival time. It often discourages the passengers for excessively waiting long time at bus stops and makes them reluctant to take the public transport, buses. To enable the passenger to track the vehicle or bus an electronic device is installed in a vehicle is known as Vehicle tracking System. This paper proposes a bus arrival time prediction using GPS and GSM technology. It would also work as anti theft system and cheapest source of vehicle tracking. It is an embedded system using GPS (Global Positioning System), GSM (Global System for Mobile Communication) and Microcontroller for tracking the bus. The real time co-ordinates obtained from the GPS will continuously monitor a moving vehicle and report the status of the vehicle on request to passengers. The GPS/GSM unit is mounted on the bus sends the data to the central monitoring system microcontroller using the GSM module and displays bus location name on the LCD. The position i. e Latitude and Longitude of a vehicle from remote place is sent by the GSM module to the Server and then the server calculates the arrival time of the bus and sends to the requested user through GSM module.
