This project designs an access point which provides for a dynamic passenger information system (PIS) available on public displays at bus stops and bus terminals. The access point is microcontroller based and is designed using the Arduino Uno. In addition, an Android device with a GPS transmitter app is placed in every bus which is to be tracked. The application sends the GPS coordinates every 2 minutes to a GSM module which is placed at the bus stops. The GSM module communicates the location information with the Arduino and the current location of the bus is displayed on an LCD screen.
