Sjoberg Responsive Urban Bus Stop

          This solution for the urban bus stop problem was derived from the changing occupancy as the bus approaches, the movement of people through the space, and the need for a visible formal change to signify the approach of the bus. When the bus has just left and will not be arriving for some time, the form defines a smaller space. As the bus draws nearer, it expands to adapt to the now greater occupancy. This expansion in three directions will extend toward the two directions of approach, and shelter the occupants as they line up to enter the bus. The expansion will be easily readable from a distance and serve to convey the buses proximity. This form uses sets of catenary arches which create a stable structure and light appearance. In the script, The time until arrival is used as a divider for the step size of the rotation of the catenary sets.
