The project “GPS GSM Integration For Enhancing Public Transportation System” is an attempt to design a tracking unit that uses the global positioning system to determine the precise location of a vehicle and through GSM modem the vehicle location is transmitted to remote user. This system contains single-board embedded system that is equipped with GPS and GSM modems along with processor. During vehicular motion, its location can be reported by accessing a website. The website maintained has the vehicular information in its database. Information from the GSM to the website is send via SMS. The location of the vehicle is traced in Google map which users can obtain through their mobile phones with internet accessibility. Similarly, at the station the audio information about the status of the bus is broadcasted along with displaying it on the LCD which helps passenger at the station to know the status of their vehicle and helps the visually impaired person to board the bus.
