Every day thousands of people board trains and buses in Puget Sound using ORCA cards to pay their fare. We used data from these cards to visualize the flow of ridership throughout the day. The size of each circle represents total boardings over an eight-week period in Winter 2020.

Click to select a transportation mode, or filter by passenger type. Drag the slider to watch the flow of passengers throughout the day. Hover over a station to view the weekly boarding count.
