Bus Monitoring System Using Polyline Algorithm

Due to rapid growth of population, every country needs an efficient public transportation system. As the density of population is increases, it keep higher burden on public transportation like city-bus etc. Therefore there is need of smart system which provides real time information to passenger of bus. The system will manage the data about current location of bus, and by using this data the real time tracking of bus will be found out and provided to passenger for bus current status. The system is developed using technologies like GPS (Global Positioning System), Google maps and GPRS (General Packet Radio Service) (3). The system includes mobile application, which services user by tracking the real time location of bus on Google Maps, time table for specified bus and locating the nearest bus stop. The system consist GPS enabled device like mobile phone embedded in bus, which find out its current coordinates periodically after some interval and send it to database for being processed and analyzed. The GPS module is implemented on bus and client side. The bus side GPS module locates its coordinates and sends it to central database periodically for further process and analysis. The bus side module is supposed to send the current bus location after every fixed interval time. And this coordinates information with timestamp are sored in database Whereas the client side GPS module is used to find out current location of passenger and calculate nearest bus location from database. The system communicates through internet using GPRS. Google maps are used for graphical representation of location of bus on city map.(3) The system will uses already stored map of city with its various bus stops and their coordinates. This map can be used as blueprint of city which is uses to compare and then locate the bus location on city map. This system can be made available to public to access as mobile application. The application can be installed by passenger for real time location of bus. The system will generate request for database on user's requirement. The mobile application can access the latest coordinates from database and plot them on Google Map for specified bus on user request. The database is analyzed, maintained and stored by central authority. This database is used to service the user in real time.
