Abstract

When planning long-distance train journeys, a traveler can usually choose between several possible connections from start to destination. The available connections may differ in the number of transfers, travel duration, and intermediate stations, to name just a few. The user's preferences determine which of the alternatives he or she selects. Additional decision criteria arise when information about expected delays of the trains is presented next to the available connections. In some cases live delay information is available for long-distance trains, however, no publicly available travel information system contains delay information several days or weeks before the trip. We propose a new solution to assist rail travelers with train trip planning. A visualization incorporates scheduled data as well as information about expected delays. With this visualization the user is able to see which connections exist, where delays possibly occur, what the consequences of certain delays are, and what alternatives exist in case of delays. The visualization is part of a web application for planning train journeys. The user is able to analyze available connections and adapt the visualization with respect to his or her preferences. Within the scope of this work we gathered what possible user preferences are, how they vary depending not only on the subject but also on the situation, which delay information is relevant for the users, and other requirements that users demand. We evaluated our visualizations with a user study. This study did not only reveal general interest in the additional provided information but also that our representation is suitable. When comparing the results for our visualization with two existing ones, we observe a good understanding and different user behavior depending on the presented visualization.
