Abstract:This report describes the development and evaluation of a prototype real-time moving map display to support engineer situation awareness and safety performance for future U.S. high-speed rail applications. The development started with a hybrid Cognitive Task Analysis to develop Information and Functional Requirements for the display. Using basic design principles, the initial layout for an iPad-based display was created. The design was evaluated by 10 experienced engineers in a formal cognitive walk-through. After a brief training session, they answered questions about the display and performed typical actions such as entering track warrant information. Subjects completed most of these tasks successfully and provided feedback which was used to improve the display. The revised iPad display was then evaluated in a human-in-the-loop experiment. Eight experienced commuter rail engineers drove twice a 38-mile trip both with and without the display. The engineers demonstrated similar train handling performance and rule adherence in both operating conditions. They generally took 30 to 60 seconds more to enter track warrant information compared to using paper forms. Finally, the engineers thought that a similar display would be helpful for conductors and could replace paper rule books.
