CADBLOS: Android–based UML-centric design approach to campus-drive bus locator system

Abstract

The delay; lack of flexibility, convenience and uncertainty associated in bus services in university of Calabar, Nigeria necessitated the development an Android-Based Bus Tracking System, otherwise called CADBLOS, using the UML-Centric design approach, to enhance bus service system within the campus communities, using University of Calabar, Nigeria, as a case study. Software systems are continually expanding in volume and complexity, and without efficient modeling proficiency in architectural modeling and design, developers cannot be successful. These proficiencies are the imperatives to produce quality projects and products, which are far most graded superior to programming, Quality Assurance, and other requirements management. Since modeling is the core of development and UML is the de facto standard as the modeling notation, UML (Unified Modeling Language), was adopted to provide the behavioural and structural representation of the CADBLOS software artifacts. We adopted a hybrid of the Structured System Analysis and Design Methodology (SSADM) and Object Oriented Methodology to design the CADBLOS, a mobile Based Bus Locator System using android application. The prototype system was developed using the underlining technology of the Global Positioning System (GPS) and the communication services provided by the Global System of Mobile Communication (GSM). The Global Positioning System (GPS) was the main technology that is implemented behind the system. A prototype of the system developed has been tested and implemented. After all modules integration, the system is able to provide its basic function of locating buses on real time and reduce workload associated with accessing web-based bus location facilities.
