This system enhances the LTT computation and ETA prediction in order to reflect the current traffic situations.

The vehicle's position data, ETA and LTT is then stored in the database for live and past tracking. The mobile application installed on a GPS enabled mobile phone (Bus Simulator), periodically reads the current position of the vehicle using GPS technology, the data is sent via a mobile wireless communication network from the mobile phone to a Webserver where predictions such as the Estimated Time of Arrival (ETA) and Link's Travel Time (LTT) is computed. The system allows the public transit vehicle management and the passengers to view the tracking history of a target vehicle on a GIS Map through the internet.

The system includes global position determining mobile phones located in the vehicles for determining the location of the vehicles along their routes. This paper focuses on the implementation of a Real-Time Public Vehicle Mobile Tracking System using GPS Technology. Intelligent Transportation Systems (ITS) are gaining recognition in developing countries today.
