Though expressway administrators present drivers with traffic congestion information, the drivers cannot obtain sufficient practical information to avoid traffic congestion, determine how much congestion they will encounter or know when they will arrive at their destination. Therefore, we propose an interactive interface allowing the drivers to make a driving plan on an expressway with traffic predictions, and thus change their driving behavior. By visualizing traffic predictions using a diagram with two time axes, drivers can look at multiple futures interactively. Thus, they can obtain enough information to avoid traffic congestion. We compared our interface with conventional traffic congestion presentations, and also investigated its feasibility in a real environment by distributing our interface as an Android application. Our results showed that drivers were able to make a driving plan more efficiently using our interface than with conventional methods, and then follow their planned route on an expressway in a real environment.
