Abstract: In order to facilitate the introduction of transmit tracking and arrival time prediction in smaller tranasit agencies, we search an Andriod-based system which we call Tracker. To use tracker, a transit agency should obtain smartphones, install an application, and place a phone or GPS in each transit vehicle. Our goal is to require no other input. This level of automation is possible due to a set of algorithms that use GPS traces collected from instrumented transit vehicles to decide routes served, find stops, and deduce schedules. The primary information to most city transport buses is arrival time. It often dishearten the passengers for excessively waiting long time at bus stops and makes them averse to take the public transport, travellers. To enable the passenger to track the vehicle or bus an electronic device is established in a vehicle is known as Vehicle tracking System. This paper suggest a bus arrival time prediction using GPS, GSM technology. It would work as theft protection system and inexpensive source of vehicle tracking. It is an system using GPS (Global Positioning System), GSM (Global System for Mobile Communication) and Microcontroller for tracking the travellers. The real time co-ordinates obtained from the GPS device will continually monitor a moving vehicle and report the position of the vehicle on request to passengers. The GPS/GSM unit is fix on the bus sends the data to the central monitoring system using the GSM module and show bus location name on the LCD. The status i.e Latitude and Longitude of a vehicle from distant place is sent by the GSM module to the Server and then the server calculates the ingress time of the bus and sends to the requested user through GSM module. A real-time vehicle tracking system uses a global positioning system (GPS) technology module to receive the location of the vehicle, to forward into microcontroller and to connect network by a general packet radio service (GPRS) technology for displaying a real time on the website or android map developed by Google Map which allows inspection of vehicles at all times. There are the GPS and GPRS modules, the GPS module will excavate the vehicles via the satellite, and will bring together all data and redirect it to the webapplication on students device by a contoller. Here the system is handle by a bus in charge. It can notify students for several bus routes, timetables, bus location, etc. It also send notification to the students when data is updated. System also prevent to enter an unauthorized students in bus.
