Paper Title
Enhancement of PMPML Bus Services Using GPS

Abstract
Today passenger facing problem of finding the bus of his root and he does not know about exact arrival time of bus. We can solve this problem by using GPS using android system. GSM modem, provided with a SIM card uses the same communication process as we are using in today�s phone. We are using Google API which sends the Vehicles current location based on its IP address. This paper introduces a real-time vehicle tracking system using a global positioning system (GPS) technology system to get the area of the vehicle. Trilateration is used to determine absolute or relative locations of points by measuring the distances using geometry of circles, spheres and triangle. To calculate the arriving time haversine distance formula is used. Keywords- Google API, GPRS, GPS, GSM, Tracking, Vehicles.
