INTRODUCTION Bus service is one of the major transportation used by the public here in our country. Buses operate throughout the country, and they come in all forms and sizes, from small rusty boxes to large, luxury coaches that run through the highways and roads of the Philippines. For most people not owning a private automobile, the “public utility bus” (PUB) is the only practical way to travel on medium or long distances, since jeepney (PUJ) are usually limited to local routes, (Boquet, 2010). Many buses here in Philippines have full amenities. On board comfort rooms, even Wi-Fi is present. The government has plans to modernize the country’s public bus transport system which includes requiring bus operators to install a GPS monitoring device in their buses for commuter’s safety. Waiting on a bus or any other forms of transportation is stressful especially those who are working, studying and to those who have important journey (Ferrer, 2015). Without any notion or idea of the location of the bus, commuters tend to be nervous and fearful on the negative outcomes. Upon studying this field the proponent developed RESEARCH ARTICLE OPEN ACCESS Abstract: In this study, the Global System for Mobile communications (GSM) based passenger bus locator is designed, developed, implemented to solve real world problems and evaluated based on functionality, accuracy and operability. The device is composed of two different Modules, A and B. Module A is used to locate the location of the bus using GSM 908 with Global Positioning System (GPS) receiver built in and to send the location of the bus to the ones requesting via Short Message Service (SMS) or text message. For tracking, the GPS collect the data or coordinates to be process in the Microcontroller; the data that is being collected by the GPS is being compared to the pre-determined coordinate programmed in the microcontroller. The nearest coordinate similar to the program with a corresponding location must be sent to the user after requesting. Module B is used as a server to accept all the request inquiries of the commuters and to have a common recipient to accommodate all users to send in the Module A. Furthermore, the evaluation of the devise is assessed by randomly selected respondents too show that the device is acceptable.
