The big number on each stop is its detour cost: the driving time from this ramp to the stop, routed over the real road network with its one-ways and speed limits. The cards are ordered by it. Straight-line distance is real and is not what a driver cares about — a stop 0.3 mi away behind a median is worse than one 0.9 mi away off the ramp — so it sits underneath as a footnote.
