Travelers sometimes need to reach a destination in a given amount of time. However, today's navigation systems try to route users to the destination as fast as possible. In this paper, we present the concept of time-based pedestrian navigation. We use a map on a smartphone that highlights streets depending on whether they will lead to a destination in time. Our map also allows the users to choose between route alternatives during the walk.
