Low-cost campus bus tracker using WiFi access points

Campus bus service has been introduced in hope to ease students and campus community to move around, but the service has been unreliable. More importantly, the position of the bus at a given time cannot be tracked, making it even more challenging to estimate the time of arrival. In this work, a low-cost campus bus tracker is proposed by selectively using WiFi proximity technique and GPS information, where three modes of data communication methods are considered. A website is constructed to display the current position of the bus of interest, while an Android application is developed for bus driver to send his current location data at a regular interval. Experiments were conducted to verify the viability of the proposed tracker in University of Malaya campus, where the hybrid approach was found to be feasible.
