Through a comprehensive heuristic evaluation of TrainOSE’s existing platform, it became clear that the system scores low in several fundamental usability principles. Issues such as inconsistent navigation, lack of error prevention mechanisms, poor visibility of system status, and a mismatch between the system’s language and real-world conventions are prevalent. These deficiencies lead to user confusion, increased errors, and a frustrating experience when attempting to purchase tickets or access travel information. This low usability score underscores the urgent need for a redesign to address these critical problems and enhance the overall user experience.
