ABSTRACT: a common approach to get vehicle location


Due to the high cost of time several methods are proposed to reduce
the wastage of time on the bus station or waiting for the bus for more time is
not preferred. So, we require one tracking system to track the Complete
Transport System.  Every GPS tracking
system is a common approach to get vehicle location information in real-time.

real time bus position and time monitoring system uses GPS technology along
with different application to fetch data and with software that display the
data online along with different buses on different route to the user.

will make the public transport system competitive and passenger friendly. The
App “GPS based Location Tracker” is a GPS service based application which would
help us in locating the exact geo-position of people (any single entity of a
large set) depending upon their current location/whereabouts.



Our real-time
tracking management system is composed of four components: – 1) a GPS Tracking
Device, 2) a server and a database, 3) GCM & Client application as shown in
Figure 1. The GPS tracking is done by GPS enabled android mobile that transmits
location information to the
server through GPRS & GCM networks. The server is a personal   computer that receives the information and
put it in the database. The database formats the information in a special form
that can search and display using Google Earth software or Google Map.

System Building Blocks:




Positioning System (GPS) is a system composed of a network  of  24
satellites  of  the 
United  States,  which 
are originally  used  in 
military  services, and later
allowed for commercial use. The satellites periodically emit radio signal of
short pulses to GPS receivers. A GPS receiver receives the signal from at least
three satellites to calculate distance and uses a triangulation technique 1
to compute its two-dimension (latitude and longitude) position or at least four
satellites to compute its three-dimension (latitude, longitude, and altitude)
position.  Once a location is computed,
it can calculate an average speed and direction of traveling.  Therefore, GPS is a key technology for giving
device its position.



Cloud Messaging for Android (GCM) is a service that allows you to send data
from your server to your users’ Android powered device, and also to receive
messages from devices on the same connection. The GCM service handles all
aspects of queuing of messages and delivery to the target Android application
running on the target device. GCM is completely free no matter how big your
messaging needs are, and there are no quotas.



Map is very popular free software that provides maps by satellite images around
the world 5. Google Map is a version of Google Earth that shows the maps
on-line using with a web
server and a web browser.



our literature survey we found out the following existing systems that are
already being deployed at the places inside and outside India. In foreign
cities due to their economy advantage people there use this system by using
cameras and other types of sensors on almost every light or signal poles. These
devices inform the location to the centralized server and notify the passenger
about the bus. Some of the places in India like Bangalore the system exists
with application that runs on either only on web or in the high configuration
smartphones with highest data. These devices make the purpose easier.







Tracking Module:

GPS Tracking Module is based on the GPS enabled android device. The android device
must be based on version 4.4 or more. This type of mobile device can have the
access to GCM service. Android Mobile in the vehicle gets its position using
GPS. From that position we get the latitude, longitude & time. And we have
to send that position to App Server through GCM. This process repeat after
every 2 or 5 minutes i.e. set by Admin of the system.


In the working stage there
are four phases in          which the
task is divided into:-

Capturing the Current Location of the Bus.

Take Input from the User.

Entering the Coordinate Values of the
Respective Bus Stop into Database.

Calculating Time, Position, Phone Number and
Display to User.

workflow of real time bus position and time monitoring system start first with
GPS module sending the data to the computer system which will update the
database with current longitude and latitude.

the same time user from GUI end can enter the source and destination along with
the required bus number and press find command Then it will search all bus
routes through which bus will travel.

the same time computer system will update the database with current bus
latitude and longitude value.

search will lookup database for the bus range if yes then it also search for
all the bus stop within the range and check
active bus to the source along with search
bus then match the bus location with passenger source location and calculate
the time required to reach the active bus at passenger location .

will display the time and location of the bus to the user. This entire process
will be repeated again and again for every search done by user.


GPS Device: Android Mobile

Processor: 1GHz or more

 RAM: 1
GB or more

Internet Required


this paper we have proposed a GPS tracking system which will track the current
position of the vehicle and show it to the user who wants to travel by the
vehicle. The system will reduce the waiting time for travelling. The GPS
Device will send vehicles’ current position to the server. The server on
request from the client will show the client the current location of the
vehicle on the Our Map.
