A map of the Tokyo area zoomed in to show the links used by mode for the simplex algorithm (top) and generated trips to-work (bottom) filtering out edges with fewer than 10 traversals. Blue lines are trains, green are buses, red are roads, purple are interhex links, and connecting walking links are orange.
