Centralized Traffic Control, commonly named CTC, is the most common way nowadays of controlling train traffic. It is based on the principle of centralizing all information concerning railroad tracks over a given area and to control trains running on it by the mean of a single person, the train dispatcher. This technology needs efficient telecommunications as the employee who dispatches trains is not physically present at a station but more commonly at a remote place, namely the CTC office. The CTC retrieves railway signals and gives useful information to the train dispatcher using good design Graphical User Interface. Although it was a completely hardware device, CTC is now most of the times a software which summarizes signals, headways and trains to allow the train dispatcher taking good decisions, particularly when some trains stop or have delay. Some of CTC are even partially automatic and can take routine decisions by themselves, letting only critical decisions for human control. It also most of the times prevent human errors by avoiding decisions which could result in train collisions. This thesis objective is to design and analysis of Graphical User Interface for Train traffic control system for Ethiopian Railway Corporation. In this context, the CTC is the run time user interface and alarm handling facility for the stationary part of the system, subsystem for Centralized Traffic Control. Therefore, based on international standard graphical user interface design process, this thesis will provide analysis by compare and contrast selected candidate frameworks. One of the candidate framework will be current ERC GUI framework. And based on its merits and demerits the report will recommend an appropriate framework using standard specifications.
