Enhancing Public Transportationpaper proposes and implements a solution for enhancing public transportation management services(Bus) based on GPS and GSM. The system consists of four modules: Bus Stand, In-Bus Module, BASE Station Module and Bus Stop Module.

Equipped with PC and GSM modem, Bus Stand Module sends the initialization information containing the Bus number and license plate number to In-Bus Module and BASE Station Module using SMS.

The microcontroller based In-Bus Module consisting mainly of a GPS receiver and GSM modem then starts transmitting its location and number of passengers to BASE Station Module.

BASE Station Module equipped with a microcontroller unit and GSM modems interfaced to PCs is designed to keep track record of every Bus, processes user request about a particular Bus location out of Bus Stand and updates Bus's location on Bus Stand. Bus Stop Module is installed at every stopping and consists of a GSM modem, memory unit and dot matrix display all interfaced to a microcontroller.

This module receives Bus's location information coming towards that stop from BASE Station module and displays the information on a dot matrix display. The results have shown that the developed system is useful for facilitating people using public transportation services
