The main goal is to create an application that tracks the bus's dynamic location using a GPS-enabled device that retrieves the current coordinates of the bus as well as the timestamp. These coordinates are then saved into a database. The operation of retrieving and plotting these stored coordinates will be performed by a client process. This allows the users to locate the bus on the map. The developed system will use a producer-consumer model, with the GPS equipped device fetching live coordinates acting as the producer and the application plotting these received coordinates on a map acting as the consumer. The platform that is created uses API calls which has an advantage to be integrated with other applications. A web-application which plots the dynamic location of the bus on the map. This design uses low-latency, near-real-time data that allows the proposed system to track coordinates in very short periods (sub-second), improving the tracking system's overall precision. As this system employs a NoSQL-like database it is based on BASE characteristics. This permits data values to alter over time due to its Soft State characteristic. As a result, the data might be updated amidst hundreds of data reads, resulting in reduced latency and near-real-time results. This paper proposes the web application architecture for tracking our college bus service which lets the students and faculty to track the bus with ease.
