Prediction of bus arrival time using GPS/GSM technology

Abstract

In the daily operation of a bus system, the movement of vehicles is affected by uncertain conditions as the day progresses, such as traffic congestion, unexpected delays, and randomness in passenger demand, irregular vehicle dispatching times, and incidents. It often discourages the passengers for excessively waiting long time at bus stops and makes them reluctant to take the public transport, buses. In this project we propose a system by which we can predict bus arrival time using GPS and GSM technology. It is an embedded system using GPS (Global Positioning System), GSM (Global System for Mobile Communication) and Arduino 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 using the GSM module. 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 LCD Module mounted at bus stop through GSM module.
