Summary

Demand above downstream capacity accumulates upstream, while merge priority remains a separate assumption. Based on Nelson and Mowrer (2002), p. 3-372.

Original illustration for Hydraulic evacuation model, level 3 Advanced.

Source basis: Nelson and Mowrer (2002), p. 3-372. Create an original visual; redraw, do not copy source figures.
Alt text: Two occupant streams merge before a bottleneck, where excess arrivals form a queue.
Accuracy notes: Add total flows, not specific flows without width. Do not assign equal priority as a physical law.
